In recent years, such as Nadella Indian faces, more and more appear in the Global 500 companies. US media and even comment on, India is evolving as an ever 'produced' 21st Century CEO magic kingdom. Why Indian executives can successfully break through the occupation of 'ceiling', sits at the top international big companies? Indian executives 'occupation' no shortage of Indians in Silicon Valley, Silicon Valley executives of large companies, such as Google's top 13 executives, Indians have four. As early as 2005, according to a survey the University of California, Berkeley, Stanford University jointly conducted found that 52.4 Mens Nike Nike Air Max 2015 Men Free 3.0 Wool Skin Shoes Blue Yellow percent of Silicon Valley technology companies have an executive and technical leaders from abroad, accounting for 25.8 percent Indian. By 2012, Indian leadership talent accounted for 33.2 percent of the company. About an important reason for the outstanding achievements of Indians in Silicon Valley, the Indian media that: the first technology companies in the United States discovered the Indian IT capability, then Indians began to help other Indian in Silicon Valley has established a network of Resource Network These have a strong influence in the technology company personal network resources to enhance the professional competence Indian executives. Shanghai Jiaotong University Antai College of Economics and Management, Professor Ren Jianxin standard view that Indian executives come to the fore more important competitive force, 'is in fierce competition, innovation and development capacity in case of limited resources.' In fact, a number of important Nadella is Microsoft's technology for one of the developers. This innovative capability is reflected not only in the technology sector, while private equity firms 克杜瑞 partner of Unilever former senior president Wendy Gbarnga (Manvinder Singh Banga) or Nike Free TR Fit Indian subsidiary of Unilever staff, in opening Indian rural market in the process, we employ innovative Indian women as their distributor, and then give them loans to purchase Unilever products so they sell things to Air Jordan Outlet other people in the community, not only for Unilever to establish a new sales channels, but also to solve the employment problem of some women. Wendy's brother Ajay Banga Banga (A jay Bango) from Nestle started his career, he has since become CEO of Citigroup Asia-Pacific region, and became MasterCard International President and CEO in 2010. He led the MasterCard in India made an innovative fingerprint payment trials. The Indian government collected 600 million farmers fingerprint records, state-owned banks are open to these people and to set up a bank account for the hope that by the MasterCard help to achieve transaction through fingerprints, but at the cost of rural India to install fingerprint recognition device is too high, MasterCard phone installed on the fingerprint reader, transmitted to the MasterCard system via mobile phone system, now whether it is rich or poor farmers, can use fingerprint payment in their villages to buy their daily needs. Advanced business education although India is the world's largest software and service outsourcing back-end big country in the field of Nike Air Max IT technology has the advantage of high-end talent cultivation, but in other areas, India has a lot of 'export' to executives of large international companies, including many former CEO or CEO. According to the study the US 'Time' magazine on the S \u0026 P 500 companies found that the number of Indians as CEO after the Americans. Also, Indian managerial talent management practices not only appear in the field for more multinational companies and start-ups in any Jianbiao told reporters in the field of management education in business schools are also a growing number of Indian president. 2010, the United States appointed by the famed Harvard Business School's Indian Nitin Nohria (Nitin Nohria) for the 10th Academy dean, has become the dean of the prestigious first non-American on the 102 years of local history; Chicago Indian School of Business also select Sushi Kumar (Sushil Kumar) as the new president; in Europe, the former honorary president of Northwestern University's Kellogg School of Indian origin Deepak Jain (DipakC.Jain) 2011 also served as Nike Air Max 2015 Men dean of INSEAD post. 'History and benefits management education is one of the important reasons for Indian CEO after another.' Dean of East China University Wu Bai were on the 'First Financial Daily' correspondent said that although India's economic development level is not very high, the overall education level is not high, especially basic education, 'but its high degree of internationalization of higher education, has a long history of education in economic management talent into the international market.' As renowned Indian Institute of Management (Indian Institutes of Management , IIM) Ahmedabad campus in the 1960s and co-founded the Harvard Business School, created in the last century 50's Calcutta campus is set up with the help of the Sloan School of Management Mens Nike Free 3.0 Wool Skin Shoes Blue Yellow at MIT. Compared to fifty years India has been to train and specially trained management personnel, China only in the 1980s and 1990s began to implement modern management education, and gradually establish a business school, Wu Bai said that the 'Chinese management education aspect of time is not long enough, it is difficult enough to cultivate a large number of experienced, stronger comprehensive international management talent, but in recent years, the rapid development of Chinese business schools, Chinese Nike Free TR Fit executives 535807 103 Jordan CP3.VI White Black Game Royal Sport Red CP3 Shoes 2013 Sale are large international companies emerge. 'break' ceiling 'In some large multinational corporations, executives from emerging market countries often encounter swallow' ceiling ': to the highest positions in the market of their own country, but on the way to the company headquarters core management of the road, but always in sight. 'Chinese executives, especially those who are not Mens Nike Free Run 3 Shoes Black Red 3 Air Max 2011 Womens Grey Green Black learning in Western Europe or North America, local homegrown, but to go out from 2015 Nike KD 7 Kids Basketball Shoes Sport Turq Charcoal Atomic Green Outlet the Chinese mainland, the existence of inherent deficiencies in social skills, communication skills, etc.' A German-owned multinational senior Chinese vice president, told reporters. He also found that the United States or European corporate executives there is a relatively 554988 100 Nike Zoom KD V Navy Red Online closed circle, where the school, what club to join, to a certain extent, the formation of a lot of outsiders is difficult to understand manners or common-sense things. Why more Indian executives to break such a 'ceiling' barriers to it? 'The existence of a glass ceiling but also with the language, life, thinking habits.' Ren Jianxin standard, said, 'Compared to Chinese executives, the Indian executives speak English since childhood, and this is a global business language, and the language behind is closer way of thinking and cultural integration. Some of them, though, is of Indian descent, but grew up in America, with a way of thinking can be better integrated into American society. 'And Wen Di Gbarnga has said India Life is a grindstone in his life, and exercise their ability to adapt, which is multinational executives to address new markets and uncertainties in the necessary capacity. four reasonsIndian executives 'occupation' of Silicon Valley ]]> https://ameblo.jp/conceptbm/entry-12070457417.html Mon, 07 Sep 2015 16:02:11 +0900 Nike Free Run Womens also try to move the payment demand. These applications provide a convenient method of payment, 2015 Nike Free 5.0 realize the commercial value of more applications. But the analysis of the current market there are numerous applications pay 2015 Nike KD 7 Kids Basketball Shoes Sport Turq Charcoal Atomic Green Outlet hundreds of models class application design, they found more than meet the user in normal transactions, there are five easily overlooked experience points, unknowingly allows users to play your product image the fold. So how do you avoid it? This article gives some solutions. 1. create an 'insecure' atmosphere 2. The quasi-physical shape of the user's thinking and not compatible with the traditional payment methods 3. 4. Fill in the novice user 'blank' 5 will be paid into the scene one create an 'insecure' atmosphere Security is based on the payment of any product. But for users, security is not just as simple as not losing money, you need a sense of security of the payment environment. Negative examples allow Mens Nike Free 3.0 Wool Skin Shoes Blue users to have the feeling of insecurity are undesirable. What will Mens Nike Free 3.0 V2 Shoes White Black Red be the feeling of insecurity? Such feedback is not timely, the system status is unknown and the like. Positive cases eg1: in between the lines are to inform the user of all changes in processes for safety sake, the copy emphasis on 'security' and 'encryption', from the user's point of view to worry about statements tested. eg2: When reading tasks or changes in capital and other private data password multiple times. China Merchants Bank ATM machine processes pioneered this way, when the user makes sensitive operation is again input a password. eg3: graphical lock or face lock enhanced input convenience and fun to use. In addition, because the graphics than words easy to remember, easy to use graphical lock can set a variety of passwords, such as the commonly used Mens Nike Free Run 3 Shoes Black Red 3 password, payment password. 2 quasi-physical modeling of users, rather than thinking for the user to better understand 'Your phone is your wallet', many products using materialized design ideas. Materialized design, original intention is to let users in the use of new things and old things the association to make it easier to understand new things. However, we see a lot of materialized design, structure almost real wallet copied to the phone interface, not knowing wallet 'Industrial Design' (temporarily so to speak :)) and interface design is not the same two ideas. If rigidly industrial design modeling to adapt the interface design, then the result is increase the cognitive load of users, your application will be because of the simulation of the added design elements and appears bloated. Cards negative examples entity can come up from the slot. The current situation on the interface card, Air Jordan Outlet the user can not physically touch sensor slot on a flat glass, so there is no 'out' gesture response. At this time there are no controls if more guidance, the operation is more convenient. Positive cases materialized prospective users should pay attention to the existing mode of thinking, rather than the shape itself, using the interface behavior is very important. In short: the simulation of thinking is the real materialized. eg1: shape card shape, allowing users to produce cards have front and back of the association, which is correct, but the reverse side of the same size does not fit too much information, so give users turn card card face demands to extend the feedback, zooms the current card face into a larger area. You can put down more mobile Mens Nike Free 3.0 V2 Shoes White Black Red features and interface characteristics of the control. eg2:-kind card slot, users can put in different combinations will be classified cards, bank access, the shopping and the like. So, how to translate this action into the interface language? Tags. Marked with the same type of label or icon to help you complete this classification. 3. compatible with traditional payment methods we have to redefine the mobile terminal payment, it must also consider the mobile terminal can Nike Air Max be compatible with traditional payment methods. For example, when traditional bank cards not credit card, you need to focus on design details, maintaining the user's patience. Negative examples of typical user tasks: a bank card entry Zhang existing application inside. Operation that is individually input box card information. If the user does not steely willpower want to use your product, how to adhere to get down. If you just do pen input alternatives, it is not designed mobile experience. Positive cases eg1: We see a lot of use to take pictures, scan, incremental regulator to enter practice. Fast your physical card into your wallet. eg2: If you really need one by one to enter information, then may be more convenient 'full assistance' approach: immediate identification card type, card instantly alert after the three-digit, wrap etc., so that the user's input 'fully lazy' ʱ?? Also automatic input intervals Nike Air Max 2015 Men can also reduce the input costs of the Air Max 2011 Womens Grey Green Black user. eg3: The above said information Air Max 2011 Womens Blue input, and output information. SMS and other means of communication for the telephone, you can call the phone communication device directly. 4. Fill in the novice user 'blank' When we Nike Air Max 2015 Men buy a new purse, almost did not say do not use, while on the phone this thing really happen. In the era of man-machine interface, each face of the new products will become the novice user, regardless of life experience. We need to design to solve, rather than letting the user to explore. Quasi-physical design is one way, but it does not last long, because the interface has interface behavior. If you learn from the practice of social products, the 'content filling' and 'registered' synchronization is a good choice. User login first register negative examples, but after the success they see a blank, even some unintelligible copywriter 'No nearby business (no business nearby).' 'Blank' may be a problem most of the products will be designed to pay encounter. At this point we think the benefits of the proposed design materialized, even nothing, users also know they can go inside the new one card slot, and interface design requires full guide. For example, the following figure, as a novice user, these two interfaces you will use what? Positive cases e.g.1: first use, after login. Let the new user tries to enter the card scanning application, and then let the user to establish the account login. After this time logged in, the user can see the wallet has a card. e.g.2: Nike Free TR Fit management by objectives. Payment products need an account, and many new products lack the user's account, then let function guidelines and Registration page appears on the screen at the same time to help users understand the registration of return, let hardships of registration becomes meaningful. 5. The payment will be paid into the scene as a carrier purse, is a since ancient times was our items close at hand, habits very mature. In the mobile era, designers can redefine the payment behavior, play online anytime, anywhere mobile Internet can be personalized recommendation features, allowing users to more naturally when mobile payments. Opposite case let the user count less how much money purse, which increased several cards, then carefully these information into the phone, like a financial accounting of the above, then this is the design notes in the application. Positive cases e.g.1: User Data Management. According to the user's name for each customer leaves business users 'tag.' The user is ready to buy something, just open the application in the history of Nike Air Max 2015 the label, the seller can be based on user information (including the face, name, records, etc.) to match the processing of payments. eg2: complete the appropriate tasks based on the user's location, it is often said that 'geo-fencing.' When a user approached the store, food cart or other locations, pushed to your phone related card coupons. When you want to use a coupon, the phone to help you find the nearest location of consumer spending. Written in the last has a growing number of mobile applications change the way we live, we have also become increasingly dependent on these mobile applications to better life. Continued fifth point 'will pay into the scene,' mobile payment will bring us a new payment experience, then maybe your wallet still, maybe you do not call mobile payment products 'XX wallet' But what will you be able to pay more, pay more and more rich way, let us look forward to that day!explore mobile payment experience: five things can not be ignored ]]> https://ameblo.jp/conceptbm/entry-12070457166.html Mon, 07 Sep 2015 16:01:32 +0900 Nike Free Run Womens the set is not uniform Android, lack of documentation, lack of attractive dark theme, as well as ambiguous burger menu abuse. Material Design solves many problems. Today it provides a unified design language, brighter, Nike Free TR Fit rich colors, and thoughtful design behind the guide as a solid support. But despite its beautiful color, use of the card provides a strong sense of depth and sense of control. I often ask myself, Is this really so many designers like to say, better than Apple's iOS design? I want to express my opinion, I think it's just inventive, not fully win. IOS and similarities of our three core principles iOS Speaking from: clarity, compliance and depth. Clearly refers to the text read, icon obvious contrast. Clearly defined, it is specific for different platforms. For iOS and Android users, what is clear depends on what they are familiar with. iOS users can instantly recognizable icon, Android users may not, and vice versa. Depth is another principle common to the two platforms. But they express this concept in a different way. iOS advocate blur and fade, Android but stressed that the concept of projection and paper. Quasi was 2.0 although all say, two platforms are used in important ways to reproduce the real world. They fuzzy, projectors, as well as compliance with the laws of physics and spatial Mens Nike Free 3.0 V2 Shoes White Black Red relationships animations present a materialized. Quasi were designed using a familiar metaphor, it helps introduce new concepts, but excessive subtle texture and three-dimensional effect is absolutely suicidal. As a user, as technology for us is not so strange, we no longer meet the quasi-physical design. Leather calendar and vinyl records, in this era has been less than the digital concept. Digital design, making obsolete the old concept and inexplicable. Nobody then such a calendar. Both languages ​​have their own weaknesses. For example, multi-layer fuzzy superposition, a kind of fragmented sense. Also, a little too bright. The concept of the card on a circular screen looks different. Card occupies the entire width. Text alignment feel uncoordinated, because there are a lot of unnecessary blank. On a circular screen, the list is also difficult to use, because the corners hide important content. However, these Android Wear interface looks great. Really gives a special feeling for the circular screen design. Content in Material Designs in obedience is not a core difference between these two lies. iOS is completely content priority, while Android uses Air Max 2011 Navy Blue Black the card to make the concept seem more content to the touch, although this loss will be around on both sides of some important screen space. Dazzling colors also overshadowed the content. Gorgeous hidden content, Nike Air Max hindering the interaction. Color, navigation and have a strong call to action focusing effect. (This is a new Material Design Lite, the web was born) contrast in iOS, focus more on content. More neutral color interface, in line with the context (which changes depending on the content). Minimize the use of vibrant colors, usually Mens Nike Free 3.0 Wool Skin Shoes Blue Yellow for operating items. Simple comparison Apple Music and Google Music shows Material Design uses Nike Air Max 95 Men more bright colors and illustrations. For Apple Music, the only use of bright colors is the 'Try Now' button. Hamburg menu tab bar VS burgers on the menu should be used if the dispute a long time. From the end yet in sight. Although Apple is rarely used in the design. However, to say the least, since the Material Design encourage the use of, we are more often seen them on Android. iOS prefer the tab bar as navigation. Interestingly, LukeW point out notably better. Facebook's iOS version switch to the tab bar, the user stickiness has been a major improvement. Google Inbox using the Hamburg menu. But sometimes hamburger menu is a good idea, such as the most important element on the page. Hamburg options within the menu must only be minor, such as settings and logout. Material Design prominent use of color using color. Of course, they are very beautiful. Flat UI color scheme too. As we all know, soft colors in various situations effects are good, unlike those dazzling CSS or Xcode default color. iOS Air Jordan Outlet color (left), Flat UI (middle), Material Design Palette (right) Material Design but to use those colors in the page header, Nike Air Zoom Flight The Glove and sometimes overshadowed the content. Many colors competing to show the importance of other elements will be reduced. The header can operate it, because it has color? You should use pictures to show my product? 'Goals' Why this title and link the same color? Color does have 2015 Nike Free 5.0 meaning, but the meaning is very limited (for example, red means alert, yellow means warning, etc.). Color also can convey the brand, but the brand should occupy the center of the interface. In fact, the application icon is the most suitable place to exhibit brand. Unless you are sure you want to use a single color in the header, or in relation to think more expressive way. In some ways the exact performance of your application. Again, this makes sense for Android, iOS does not. If a picture is worth a thousand words, a color only ten words wins. Each whole common platform to platform customization VS have to admit, I used to think the whole platform unified set of design language is the Nike Air Max 2015 Men best approach. Unfortunately, this will lead to the design language used to design iOS Android applications. From my point of view, it does make sense, but in the end user unfriendly. Android user is not familiar with the iOS. Target Material Design unified whole platform is a brave attempt, is doing the best I have ever seen in this context. But this really is the best way to it? Gorgeous on the website really need it? Card for the small screen it? The concept of the card on the Android wear, sometimes round the screen, really work? Giving the impression that this language does not give priority to equipment. Instead, like hindsight. Take a look at Apple Watch, it is designed solely for Nike Air Max 95 the watch and rethink too. This means there will be new UI paradigm to consider, especially for press, digital crown, wrist detect and black edges of the screen. Material Design define more clearly how to combine and how to operate from the material selection, the color, everything is explained in the Guide. How Each design element should be used to create a unified structure and projection. Have a specific color scheme and color combinations. Material Design even provides a set of system icons. Has a strict style guide, the benefits are not easy to go wrong. Like Bootstrap. It provides a unified Nike Air Zoom Flight The Glove and convenient system. The disadvantage is that it limits creativity, most applications will homogenization. Material Design of glittering do not get me wrong, there are many places Material Design done well. Just seems every designer did not seriously consider its shortcomings, the high praises. Design rules never changing, the people's lives to the forefront of the times. As long as we live in changes in the design will change. For example, their new design details is superb. On a number of design issues have made guidance, let you out of the field of Material Design also be harvested. Material Design of color and animation guide really impressive. The concept of the card performed well throughout the platform. It is scalable and modular. Of course, also applies to the page - before moving the wave coming, designers have been using for a long time. But I believe the smaller the screen, the more it is useless. I mentioned before, pastel color is not a new thing. But Flat UI trend and Material Design are respected it. We are back to nature, to create a coordinated colors and beautiful fonts. This is a good thing. The more we understand the basic design, we can better shape the upper design. Material Design animation elegant, Air Max 2011 Navy Blue Black pleasing, though not so people understand innovation. Before iOS7, transition style interface is still a very new concept. Very pleased to see two sets of norms are respected Nike Air Max 95 Men more smooth, progressive animation to gradually guide the user, rather than be noticeable by the sudden change. Material Design meaningful animation. There is no perfect design language will never have perfect design language and templates. The purpose of this article is not to criticize one of them, but from the perspective of strengths and weaknesses to look. Design is for a purpose to select the most suitable way. So go forth, continuing experiment to find the product that best suits your. Do not forget to consider the equipment used by people. I often write some articles on iOS, Android and code. You can find me on Twitter viaMengTo. Thanks for reading!Material Design is inventive, not fully win ]]> https://ameblo.jp/conceptbm/entry-12070456847.html Mon, 07 Sep 2015 16:00:35 +0900 Nike Free Run Womens two people is the core concept of a preliminary understanding (actually because they are engineering students), but others in the group but then the kernel ignorant - they are waiting for me to They explain explain. Well, for those little Nike Free TR Fit engineering students the basic concepts, the preferred method is to play an analogy about cars (at least get a male audience). However, in practice what you can on the car compared to the kernel to do? You can not be compared directly to the core engine or chassis, and even the vehicle's path. When you try to explain what a kernel programmer to take advantage of the operating system doing even worse. When the car body as a metaphor for the kernel in the end what is it? A kernel programmer and can not be directly defined as a mechanic. So, the definition of the class of car designers do? After a long period of intermittent explanations and hesitation, I tried 先向 group of girls explain, it's like the kernel developers for automotive design laws of physics run. Unfortunately, they Mens Nike Free 3.0 Wool Skin Shoes Blue Yellow still do not believe it. Do you have a better explanation? 'The Matrix,' released in 1999, so I soon became interested in the operating system, and finally I was FreeBSD (a free Unix systems) project to become a kernel developer. But at the same time, I have been fascinated by learning and The Matrix, he spent a lot of time. Sometime in the early twenty-first century, probably in 03 or 2004, I wrote an article, I will, 'Matrix' characters and what they happen and its sequel with a (virtual) operating system analogy of a system. In order to save the old article down, prevent the loss of contents in the forgotten server, it will be moved to the cloud, I copy and paste in the following initial content of the article. Tip: You can extended the metaphor further. ----------------------------------------- Since the operating system design, implementation and maintenance It is one of my greatest interest, and the first time I watched the 'Matrix', so they are some of the concepts of the movie were thinking, and think to some extent they exist similarities with the operating system: The Matrix World: the equivalent of an operating system (ordinary world in which we human beings live, the kernel ('Matrix' itself)) has a user space are running. Obviously, this is a rather defective operating system. ʱ?? ʱ?? People: the equivalent of the process, including the kernel and user processes. General process, 'non-privileged' process and background process with root privileges ('agents') have a lot of difference. Daemon with root privileges can use privileged ports, destroy random process, memory management and so on. Matrix: the equivalent of the kernel. It appears to be based on the Nike Free TR Fit core structure of messaging, rather than micro-kernel structure (some parts even though they have micro-kernel, such as having a large number of kernel processes, among processes are strictly independent, and messages have Nike Free Womens been mentioned in passing mechanism). The kernel manages all processes, as well as on Air Jordan Outlet the progress of the operation (such as maintaining an active process, the process of service recovery process). But this is still an obvious 2015 Nike Mens Nike Free 3.0 Wool Skin Shoes Blue Yellow Free 5.0 security flaw: Some user processes can transfer part of their code into the kernel space and execute (because of a bug). Only certain system calls affected (like 'phones'), which expands the privileges of the user process tamper return stack, so if the process receives a signal, it will produce mistakes and garbage collection ( If you are killed in the Matrix, then you really dead). Oracle: the equivalent process (task) scheduler. It has all the data processing monitor (resource utilization), and in advance (which obviously) know how their optimal scheduling. Agents: equivalent systems monitoring / intrusion prevention / protection system has heuristic operation (IDS (Intrusion Detection System) / IPS (information processing system)). Most of them have a core part (or kernel module) but basically it is Nike Air Max those background processes with superuser privileges to run in user space. Their duty is to find the process of trying to break into the system and destroys security. The trainman: the equivalent of the kernel and user space gateway / messaging queue. If you want lawfully in user space and kernel data transfer must be done through here. Of course, you may never trapped in the queue queue. The Merovingian: the equivalent of network / IPC (interprocess communications) stack. Its duty is to master the process between what Mens Nike Free 3.0 V2 Shoes White Black Red happened. An accidental error input / output data will be manifested in the form of a bug. Vampires / ghosts: the equivalent of the old version of the API / KPI compatible device. Due to historical reasons, these codes are not perfect, but the code and some kernel process is not complete but Air Max 2011 Womens Grey Green Black should not be connected. The Architect: equivalent kernel monitoring (managers) hardware, responsible for monitoring the process, destroy those processes 'abnormal' and the destruction of the restart process. Because it is a real-time system with high reliability, hardware debug and monitor clearly has the highest priority, but also absolutely reliable (and therefore, in order to reduce the possibility of error, but also reduce its complexity) ʱ?? Because it frequently availability check, resulting in excessive misconfigured, consume too many Air Max 2011 Men Blue Black resources, thus affecting the normal functioning of the operating system. Keymaster: equivalent security / privilege subsystem. It is very stable, but unfortunately relies on Nike Air Max 95 Men imperfect VM (virtual memory) system and the IPC system, so it can be utilized to process more privileges. The Plot: In the case of system is highly loaded (lots of process, frequent memory access), there is a design flaw between the VM (virtual memory) system, process management system and scheduler. This is a composite error, resulting in at least three problems: 1, the memory page is damaged or memory pages allocated to those processes that do not belong to them. Since the kernel and user-space shared virtual memory, in order to prevent exposure of sensitive data, improve security, the process can be either because the other party's memory pages are destroyed. 2, interprocess communication, which is very bad, even damaged or memory data structure than the process of loading too often caused by a deadlock, but had to wait for the buffer worse. 3, system monitoring becomes unstable, cyclic destruction and restart the process, unaware of this operation will increase the burden of additional memory and processes and worse, and finally greatly increased inter-process virtual memory page disrupted speed ʱ?? Agent Smith: the equivalent of a privileged IPC daemon, with parts of the kernel module functions. It is closely related with the kernel module, and can not pass the integrity check and a shared data structure with the kernel. Once it is destroyed off another privileged process, it can also hide in the middle of a system call in order to monitor persons restart it, this time it's the process descriptor have been destroyed, which makes most of its program code to be executed in the kernel ʱ?? It will continue to work long hours in this damaged state, carve into a loop, and the process incorrectly marked as security vulnerabilities, to rewrite some of its pages. Neo: originally a web server process user space, virtual memory, it is given the damage caused by super-user privileges as well as having a high priority CPU. Finally it got executable memory pages with IDS process Simth mixed, but not data page. Soon it began the destruction process, including Smith and its own damaged parts. The Ending: Last Smith tried to kill the process scheduler process, but this is because he is scheduled by the dispatcher, he does not do that. The system becomes abnormal is because the scheduler can not perform the task, including interrupt service, but in the dispatcher's virtual memory mirroring (again, the mirror also happens with Neo processes partially shared) in the part of the code, but Smith can still perform. Since only two processes can run, they want to kill each other. At the same time, because there is no interruption services, hardware watchdog timer do not wake up, it inserts an Air Max 2011 Womens Blue Black NMI (non-maskable interrupt), so that they wake up the monitoring system. This makes the system is in a critical state and begins Nike Air Max 95 Men to kill all processes, then restart the process of being killed to make the system starts up again. end! Post hoc analysis: the operating system when there is an inherent design flaw, especially among virtual memory, interprocess communication, and monitoring subsystem in these areas, which will lead to global memory between processes is destroyed and in the process address space to produce a small amount fatal flaw. Recommendation: To ensure proper process priority, more needs to be fine-tuned to reduce the priority inversion and imbalances. It is possible to rewrite the virtual memory system, the development of versions consume fewer resources to replace the IDS system. If the system load is above a certain threshold, the system monitors must be amended, but will not start a lot of action. Well, this is an article about The Matrix does not involve any form of 'free will' exposition.how to explain the operating system kernel to a layperson? ]]> https://ameblo.jp/conceptbm/entry-12070456511.html Mon, 07 Sep 2015 15:59:30 +0900 Nike Free Run Womens that the distance Python3 can really Nike Air Max everyone is widely used, but Nike Free TR Fit Air Jordan Outlet also takes a very long time. When everyone is estimated to be five years. And now from the time, just for five years. Python 3 has just been released from the start, after a few years to, I have been feeling for Python 3 appeared excited, and continue efforts to promote the use Python 3, will migrate to my original item 3 above Python. In the past year or two, my every new project, all from the beginning to the Python Mens Nike Free 3.0 Wool Skin Shoes Blue Yellow 3 use for development. But about six months ago, I began to reflect on their own whether it is correct to do so, and gradually, my passion for Python 3 becomes despair. Python3 from Python2 over to the first few years, we are only a few open-source projects that need to migrate it. Later, however, the project needs to be migrated as inundate appeared. For example, in Django, to achieve this migration, we need a new WSGI specification also requires a database-driven migration, then we can be migrated, then the next, users can begin the migration. So far, Django and most application of the ecosystem (app ecosystem), and Numpy and other scientific ecosystem (scientific ecosystem) can run on Python3, and several new versions Python3 has also been released, but the user who has been not how to use them. Download Python package index statistics show downloads Python3 proportion of less than 2% of total downloads. Worse, it is now almost no Python3 write code with. Although all my new code supports Python3, but I'll locally will run with Python3 and Python2 code, test. Only Travis CI to help me run the code in Python3. So, I do not have full use of Python3 written code. In some libraries use Python as a code language company, I told some of the responsible officers have had exchanges, I found basically no one is using Python3, Mens Nike Free 3.0 Wool Skin Shoes Blue Yellow but nobody intend to migrate Python version. In fact, as early as Python3.1 2015 Nike Free 5.0 issue, many people believe that users will in order to use the new features and which carried Python standard library version upgrade (of course, now Python3.3 function is also very powerful). But almost 99% of users who are not using these new features. So when we tell users, 'Python3 more Nike Air Max 95 useful than Python2!', Mens Nike Free 3.0 V2 Shoes White Black Red We actually equivalent to nothing, because these new features Python3 of no help to their favor. In addition to the above-mentioned problems is also very low usage Python3 Python language itself is not conducive to development, because the feedback mechanism between the user and the developer's almost gone. Now, only a few people use Python3, and where the new added features give feedback. And such a small amount of feedback may simply not be representative of the majority of the Python community user comments. We are constantly in the process of issuing Python3.X of this problem has become increasingly serious. Now we are still some added new features on the basis of the original features, but in the design of these features, we get no guidance they are widely used in the actual feedback. Why do so few people use Python3 it? First of all, I think it is all too little sense of urgency. Many years ago, I still would not programming, when Python2 still issued, the developer has decided to finally release Python3 up. Now think back, this decision is undoubtedly Nike Air Max 95 Men wrong, because the whole Python community and therefore meet the use Python2, and have not upgraded to Python3 sense of urgency. Because of lack of urgency, we finally lazy up. Secondly, I think it was because Python3 fundamentally not enough to make people excited. Python3 people there did not appear particularly desirable features, such as Nike Air Max 95 the removal was widely criticized GIL or better improve performance Mens Nike Free 3.0 Wool Skin Shoes Blue Yellow (because so many people use PyPy). On the contrary, many Python3 added features redundant. For example, Python3 adds many new standard library (most of which can be realized by pip install), but as for a small additional cleaning function, many experienced Python programmers because customary reasons, has been trying to avoid using them. Obviously, no one Nike Free TR Fit is willing to stop the hands of developers, try to spend time upgrade version, especially now that it seems Python2 can continue to use for some time. So now the situation? Obviously now our situation is not good. First, and most importantly, we have to have a more clear understanding Python3. Specifically, we have to realize, Python3 have been issued for several years, but for most developers are concerned, Python has not been better. Differences between Python2 and Python3 very detrimental to the entire community, we must try to combine the two. In this regard I have a suggestion: Python2.8 version can be 554988 100 Nike Zoom KD V Navy Red Online issued, and to include all of the new features Python3. It will prompt a warning when we will remove those unable to join because of compatibility reasons Python2.8 of features, such Nike Air Max 2015 as use str + unicode, and others can not support the statement from __future__ import unicode_literals situation. We must be able to allow users to upgrade in the process, to ensure consistency of language. Python3 broke this consistency, and now we have to make up for this mistake. Of course, this is just my personal recommendation, a final solution to the problem we also need to ask more approach. We must take the differences between Python2 and 3 filled up, such differences have been issued with each Python3 while getting bigger.

A, Canny detected contour on the article mentioned sobel edge detection, and rewrite the C ++ code that allowed soble consistent with matlab algorithm effect, while soble Nike Free TR Fit edge detection is Nike Air Max 2015 Women based on a single threshold, we can not take into account the 2015 Nike KD 7 Kids Basketball Shoes Sport Turq Charcoal Atomic Green Outlet low These two issues rich edge deletion and edge high threshold threshold value. The canny operator is well up for this shortfall, from the current view, canny edge detection in image contour extraction of doing is the best edge detection algorithm. canny edge detection using dual-threshold value method, the high threshold for detecting image is important, significant lines, contours, etc., and the low threshold to ensure that no loss of detail parts, low threshold detected edge richer, but many edges and not our concern. Finally, a search algorithm, the low threshold value and a high threshold of edge lines overlap reservations, other lines are deleted. Algorithm principle of this article does not canny further instructions will Mens Nike Free 3.0 Wool Skin Shoes Blue Yellow be detailed later in the image processing algorithm related articles. Here we use OpenCV function to detect the Canny edge Mens Nike Free 3.0 V2 Shoes White Black Red int main () {Mat I = imread (\u0026 quot; ../ cat.png \u0026 quot;); cvtColor (I, I, CV_BGR2GRAY); Mat contours; Canny (I, contours , 125,350); threshold (contours, contours, 128,255, THRESH_BINARY); namedWindow (\u0026 quot; Canny \u0026 quot;); imshow (\u0026 quot; Canny \u0026 quot;, contours); waitKey (); return 0;} display as follows: Second, straight line detection frequency of occurrence in the image is very high, and straight as a feature of the image elements of the image analysis has a very important role in this paper to detect the image line by OpenCV in hough transform. We look at the most basic Hough transform function HoughLines, its prototype is as follows: void HoughLines (InputArray image, OutputArray lines, double rho, double theta, int threshold, double srn = 0, double stn = 0); its input is a outline binary image, often as a result of image edge detection obtained; its output is an array containing multiple Vec2f points, each element of the array is a binary floating-point data to \u0026 lt; rou, theta \u0026 gt;, rou Representative straight-line distance from the origin of coordinates, theta angle representatives. 3 and 4 parameter represents the steps, because Hough transform is actually an exhaustive algorithm, rho represents the step distance, theta angle representatives of steps. The first five parameter is to set a minimum voting threshold number directly, know Hough principle, this argument should be easy to understand. From the output of this function, we can see, to get straight and not specified in the image of the starting point and end point, you need to calculate our own, if we want to be displayed directly in the image will be more trouble, and there will be In many ways close to a straight line, in fact, they are repeated, in order to solve the above problems, OpenCV and provides a function HoughLinesP (). Its output is a Vector of Vec4i. Vector each element represents a straight line, is composed of a group consisting of 4 yuan float, a group of the first two points, two points after a group of straight lines in the image represents the start and end points. void HoughLinesP (InputArray image, OutputArray lines, double rho, double theta, int threshold, double minLineLength = 0, double maxLineGap = 0); explain the last two parameters, minLineLength specifies the minimum width of the line detection, if less than the minimum the Nike Hyperdunk 2014 width of the discard, maxLineGap specified by the straight line at the same point, if the distance is less than maxLineGap will be merged. Here is an example HoughLinesP line detection: int main () {Mat image = imread (\u0026 quot; ../ car.png \u0026 quot;); Mat I; cvtColor (image, I, CV_BGR2GRAY); Mat contours; Canny (I, contours, 125,350); threshold (contours, contours, 128,255, THRESH_BINARY); Mens Nike Free 3.0 V2 Shoes White Black Red vector \u0026 lt; Vec4i \u0026 gt; lines; // line detection, the minimum vote of 90 lines not less than 50, the gap is not less than 10 HoughLinesP (contours, lines, 1, CV_PI / 180,80,50,10); drawDetectLines (image, lines, Scalar (0,255,0)); namedWindow (\u0026 quot; Lines \u0026 quot;); imshow (\u0026 quot; Lines \u0026 quot;, image); waitKey (); return 0; } The above program will detect the lines stored in the lines variable, we need to further draw them on the image: void drawDetectLines (Mat \u0026 amp; image, const vector \u0026 lt; Vec4i \u0026 gt; \u0026 amp; lines, Scalar \u0026 amp; color) {// will detect to draw a straight line on the chart out vector \u0026 lt; Vec4i \u0026 gt; :: const_iterator it = lines.begin Nike Air Zoom Flight The Glove (); while (! it = lines.end ()) {Point pt1 ((* it) [0], (* it) [1]); Point pt2 ((* it) [2], (* it) [3]); line (image, pt1, pt2, color, 2); // line width is set to 2 ++ it;} } actually Hough transform can detect a lot of fixed shape, such as: round, square and so on. They are basically the same principle, is to construct a matrix 2015 Nike Free 5.0 vote. OpenCV in the circle detection function provides HoughCircles, its output is a Vector of each element Vec3i, Vector contains three floats, the former two are the coordinates of the center of the circle, the last one is the radius. Third, contour extraction and described in Target Recognition should interest us first goal is extracted, and the general common steps are extracted by color or texture target prospects graph (a black and white image, the target is displayed in white image), then we have to analyze Nike Air Max the prospects of FIG further target extracted, and here is often used to extract the target profile. OpenCV function to extract the object contour is findContours, its input image is a binary image, the output is a set of contour points of each connected region: vector \u0026 lt; vector \u0026 lt; Point \u0026 gt; \u0026 gt ;. The size outer vector represents the number of image contour, which represents the number of vector of size on the contour points. Here we look at the usage of function by way of example. int main () {using namespace cv; Mat image = imread (\u0026 quot; ../ shape.png \u0026 quot;); cvtColor (image, image, CV_BGR2GRAY); vector \u0026 lt; vector \u0026 lt; Point \u0026 gt; \u0026 gt; contours; // find findContours (image , contours, CV_RETR_EXTERNAL, CV_CHAIN_APPROX_NONE); // draw Mat result (image.size (), CV_8U, Scalar (0)); drawContours (result, contours, -1, Scalar (255), 2); namedWindow (\u0026 quot; contours \u0026 quot ;); imshow (\u0026 quot; contours \u0026 quot;, result); waitKey (); return 0;} The above program contains two functions, the first one is to find the outline of the function, its third argument the instructions to locate the type of contour, Here we use the outer contour, you can also find all the contours, which includes a number of holes in the part, like the outline of an image forming figures arms and waist. Chapter 4 describes the method of contour parameter representation, the parameters of the program outline includes a description of all the points, other parameters can also be used to make the place a little straight, save only the start and end point of the line positions, the specific parameter usage can refer to the manual introduced in the function. The second function is a painting drawContours contour function, its first three parameter program setting of -1 indicates that all the contours are drawn, you can also specify the number you want to draw the outline. After extracting the outline, in fact, we are more concerned about is if these features can be converted to use contour, which is related to the description of the problem outline, then there is a variety of methods to choose from, such as the vector into polygons, rectangles, ellipses Wait. OpenCV provides in some of these functions. // Contour is represented as a rectangle Air Max 2011 Womens Grey Green Black Rect r = boundingRect (Mat (contours [0])); rectangle (result, r, Scalar (255), 2); // contour is represented as a circle float radius; Point2f center; minEnclosingCircle ( Mat (contours [1]), center, radius); circle (result, Point (center), static_cast \u0026 lt; int \u0026 gt; (radius), Scalar (255), 2); // contour is represented as a polygon vector \u0026 lt; Point \u0026 gt; poly Air Max 2011 Womens Grey Green Black ; approxPolyDP (Mat (contours [2]), poly, 5, true); vector \u0026 lt; Point 2015 Nike KD 7 Kids Basketball Shoes Sport Turq Charcoal Atomic Green Outlet \u0026 gt; :: const_iterator itp = poly.begin (); while (! itp = (poly.end () - 1)) {line (result, * itp, * (itp + 1), Scalar (255), 2); ++ itp;} line (result, * itp, * (poly.begin ()), Scalar (255), 2); // contour is represented as a convex polygon vector \u0026 lt; Point \u0026 gt; hull; convexHull (Mat (contours [3]), hull); vector \u0026 lt; Point \u0026 gt; :: const_iterator ith = hull.begin ();! while (ith = (hull.end () - 1)) {line (result, * ith, * (ith + 1), Scalar (255), 2); ++ ith;} line (result, * ith, * (hull.begin ()), Scalar (255), 2); the program we turn draw rectangles, circles, polygons and convex polygons. Final results are as follows: for communicating area analysis this is far from over, we can further calculate other attributes of each connected region, such as: gravity, central moments and other features, these Mens Nike Free 3.0 V2 Shoes White Black Red elements have the opportunity to start to write. The following functions can try: minAreaRect: computing a minimal area circumscribed rectangle, contourArea can be calculated within the contour area of ​​the communication area; pointPolygenTest can be used to determine whether a point is inside a polygon. mathShapes can compare the similarity of two shapes, a very useful function.OpenCV growth path (8): straight, contour extraction and description ]]> https://ameblo.jp/conceptbm/entry-12070455433.html Mon, 07 Sep 2015 15:56:21 +0900 2015 Nike KD 7 Kids Basketball Shoes Sport Turq Charcoal Atomic Green Outlet Every day I was in danger, those years were spent this way. Later, I felt had enough of this life, he decided to look for another life (no future coal mining.) I was very young, there is no burden, just like you. When leaving the coal mines, the government gave us a sum of money (about $ 2,500 - that in our country the equivalent of a year's salary of miners at that time). I took this money to start learning computer. When in fact, I do not understand anything. Just seen some pictures and read Air Max 2011 Womens Grey Green Black the sentence introduction. I bought an old 486 computer (which took a quarter of the money), and a printer (another quarter). I signed up for a college computer courses (school for a few months), but most are in the self-study. This lasted for about two years. Learn how to use a computer ... how to install the program, if fix them, how to use some software (Word, image processing software). A year later I was at home even on the Internet. Of course, the telephone dial. Since then, most of my money spent on network costs and telephone charges (then in our country particularly high such costs). Many times I had to quit eating meat a day, eat a meal (mostly eat potatoes, because this is the cheapest I could find food), so I can save enough money to make up for the cost. I have not told you, I have retired old mother and several brothers and sisters to take care of (my boss). 2 years, I did not buy any new clothes and new shoes, do not go out to eat dinner, do not go outside the entertainment before, no girlfriend (which obviously). Thus, I was able to access the (Oh, that magic Yahoo, Hotbot, Webcrawler, Altavista). I started to learn how to develop Web pages. Learning HTML knowledge, and some CSS knowledge, some of Adobe Photoshop knowledge, there are some Microsoft technology (classic ASP and Access / Nike Air Max 95 SQL server). It took me six months to build my first micro-site (static site without a database). This was difficult, because Air Jordan Outlet this information is very small, we are here not many people know these (especially in our country my town), my English is only general. A year later I was in a pool of Internet in our country cast out of the 'resume' (hardly a resume) (my savings are depleted). At this time, a German company found me, get in touch with me. At that time I was a tobacco factory jobs to earn a living (I do not like smoking). Two months after the German company let me go to another city interview ... a total of six people, I was the only one without a college degree ... but I got the job (obviously, I know more than them :) Nike Air Max 2015 Men I I thought I had no chance of it). They gave me the salary appears to Nike Air Max be Air Max 2011 Men Blue Black very high at the time, I resigned from the tobacco plant's work (this cigarette factory went bankrupt shortly after). Belt tightening after two years of study, I finally became a web developer, at home remote for the company to develop an e-commerce site. I am interested in e-commerce and database driven sites know nothing about, I need to learn more things. I worked day and night to learn this knowledge ... a year after my first version of the site was done ... then Mens Nike Free 3.0 Wool Skin Shoes Blue Yellow I went to Germany and worked for three months on this website. From the fall of 2002 I started this site, 2 years, I only went to this site, but also do web promotion for the Nike Air Zoom Flight The Glove Web site, through the efforts I make this e-commerce site sales expanded 10 times (from monthly a few hundred euros to tens of thousands of euros). For the coal mines, I have no nostalgia. Although there are a lot of former friends of mine left the coal mine regret, I do not regret it. Five years Nike Air Max 2015 Women later I came to the United States, until now. I still do the same web development, I would like to start a company (has begun to do). Six years ago 554988 100 Nike Zoom KD V Navy Red Online I started another fascinating thing: film and television production. So, I began to learn some new things :). Who knows, maybe I really have to change jobs ... you can!

I put my summary of the most common ways to share with you, we have more of the database design and optimization techniques, try to append to review, and sometimes a complete blog comment more exciting than the theme. Method 1: Using table partitioning technology. The first time I heard the table partition, is a former oracle training. Since there is table partitioning oracle, mssql think whether there is the partition table, when I go home to a handful of google, data is still there, in that my children just to make one promotion, so that more people understand and apply these technologies ʱ?? Table partitioning is a large amount of data tables, some way the data is divided into several small tables to store physically, from a logical point of view or a big table. First to a structure: the figure although it is not very clear expression during the execution of the partition table, but you can see the partition table to use those objects, such as data files, groups of files, partition scheme, the partition function and the like. We have a user table (TestUser) as an example, Mens Nike Free 3.0 Wool Skin Shoes Blue Yellow assume that the table to be used to store data of some Chinese citizens, each data record the provinces (Area) for each person belongs, and the name of each person (UserName), following figure shows. When the amount of data up to 1 million when the query is slower, and this time the data optimization is urgent. Before optimization, according to the structure, the data read and write operations, etc., it will certainly put forward a number of solutions. Here on a program-partitioned tables to optimize queries of the database, here in the region respectively storing data, such as Guangdong citizens stored in AreaFile01.MDF file, Hunan citizen files stored in AreaFile02.MDF citizens Sichuan store In AreaFile03.MDF file, so other provinces, in order to achieve this we have to do partitioning scheme. In doing partitioning scheme, the first to find out the partition scheme to relate to the four objects: file group, file, partition function, partition scheme. a: the file group, used to organize data files (.MDF) of a virtual name, a Mens Nike Free Run 3 Shoes Black Red 3 file group can add multiple data files (.MDF). Open SQL Manager, locate specific database, then right [attribute] to enter the [File group] tab, add Area01, Area02, Area03, Area04 four groups of files. As shown: b: and then select the [File] tab, add AreaFile01, AreaFile02, AreaFile03, AreaFile04, AreaFile05, AreaFile06 six data file (.MDF), and then specify each file belonging to the file group (group a Nike Free TR Fit file can be stored a plurality of data files), as well as the physical path of the file. Here we have to see to understand, these data files, the data is physically split up a data table. That there is a table of 2015 Nike Free 5.0 data may be stored in AreaFile01, it is also possible to store in AreaFile02, as long as some way to specify their storage rule on the line. c: partition function is to store data specified by the rule. Is to tell SQL, to how the new data partition. Create a partition function can be used to lower the SQL statement to achieve. CREATE PARTITION FUNCTION partitionFunArea (nvarchar (50)) AS RANGE Left FOR VALUES ('Guangdong', 'Hunan', 'Sichuan') d: hard to create the file, and assign groups of files, but also to build a partition function, purpose only one, it is to create a partition scheme. Partitioning scheme can use the following code to create. CREATE PARTITION SCHEME partitionSchemeAreaAS PARTITION partitionFunAreaTO (Area01, Area02, Mens Nike Free 3.0 V2 Shoes White Black Red Area03, Area04) after intense four steps, a partition scheme on the show Nike Air Max in our eyes. The next thing is how are we going to spend the partition scheme. First we create one common table, then this table to specify a partitioning scheme. The following code. CREATE TABLE TestUser ([Id] [int] IDENTITY (1,1) NOT NULL, [Area] nvarchar (50), [UserName] nvarchar (50)) ON partitionSchemeArea ([Area]) in order to see results, then insert some data. INSERT TestUser ([Area], [UserName]) Values ​​('Sichuan', 'Shaw a'); INSERT TestUser ([Area], [UserName]) Values ​​('Sichuan', 'Shaw two'); INSERT TestUser ([ Area], [UserName]) Values ​​('Sichuan', 'Shaw three'); INSERT TestUser ([Area], [UserName]) Values ​​('Sichuan', 'Shaw four'); INSERT TestUser ([Area], [ UserName]) Values ​​('Guangdong', 'Zhang'); INSERT TestUser ([Area], [UserName]) Values ​​('Guangdong', 'Zhang two'); INSERT TestUser ([Area], [UserName]) Values ('Guangdong', 'Joe Smith'); INSERT TestUser ([Area], [UserName]) Values ​​('Hunan', 'Yang'); INSERT TestUser ([Area], [UserName]) Values ​​('Hunan' 'Yang Er'); to query all the data, you can use select * from TestUser; by partition query: to use the following method: select $ PARTITION.partitionFunArea ([Area]) as the partition number, count (id) as the number of records from 535807 103 Jordan CP3.VI White Black Game Royal Sport Red CP3 Shoes 2013 Sale TestUser group by $ PARTITION.partitionFunArea ([Area]) select * from TestUser where $ PARTITION.partitionFunArea ([Area]) = 1select * from TestUser where $ PARTITION.partitionFunArea ([Area]) = 2select * from TestUser Nike Air Max 95 where $ PARTITION. partitionFunArea ([Area]) = 3select * from TestUser where $ PARTITION.partitionFunArea ([Area]) = 4 renderings: Look me a simple partition table is not already done. Oh, of course, in practice, only to grasp this point is Nike Air Max 2015 Men not enough, such as adding a partition on the original partitioning scheme, delete a partition. Method 2: xml type from the table instead of the main design, so as to improve query performance. Optimize and improve the performance of the database, it is a good database design from the beginning. In a conference reservation system, for example, a book conference system includes a meeting time, meeting place, presenters, participants, informed people, recorder and other related information. In the TDD, DDD model dominated era, here, in order to better express my wish to elaborate on the issue, or to a table-driven model for development. User needs: a: a conference may have multiple hosts, although this situation is relatively small, but there might be. b: a plurality of participants in Mens Nike Free Run 3 Shoes Black Red 3 a conference, this is not difficult to understand. c: a meeting likely to Mens Nike Free 3.0 Wool Skin Shoes Blue Yellow let someone know, this person can participate or not participate in Nike Air Max 95 the meeting, usually the top. d: a meeting might have zero or more recorders. e: a need for remote video conference, projector, computer, microphone and other conference facilities in some of the equipment. f: After meeting reservation, or important information modification meeting time, location, etc., e-mail notification participants. General database design: a: to build a Meeting of the main table to hold the meeting name, meeting location, meeting time and other relevant information. b: to build a MeetingUser table storage moderator, Nike Air Max 2015 Women participants, informed people, recorder. c: Similarly, the equipment required by the Conference MeetingDevice table used to store related information. Figure: this table structure is relatively conventional design methods, but in practice, you will find some problems to be improved. For example: a: extract the relevant information at the time of a meeting, it will join multiple tables query. Such a query on a large program affects database performance. b: In doing enough to choke modify operation, the first to amend the relevant information of the 2015 Nike KD 7 Kids Basketball Shoes Sport Turq Charcoal Atomic Green Outlet main table, and then the main table associated with the child table to delete all information inserted once again, whether such operations enough to vomit blood. Of course, some improvement, it would be more to modify the data before and after modification, and then add, delete, modify means to achieve sub-meter data updates. Such operations in some ORM operation has been achieved, but their own code when the code to achieve, especially in a number of code, I felt always that worry. Tucao so much, is there a better solution? Of course, in SQL, we can eliminate the main XML data type from the table design. Figure: The above table structure design, is not there a little fresh feeling? Obviously, we can put a design flaw first table to eliminate. A conference-related information are stored in a record of a table, so that data appears to be not more intuitive it? a: a book for more information meeting, I do not need to connect to query multiple tables, I have to do is just use C # to parse the Linq.Xml check out the XML string can be. b: When modifying the operation, I just need to regroup XML data, an Update to update the information relevant to the meetings, the operation is not much easier. On the surface of this design has been perfect, but the user's needs are endless, one day, you receive a demand, a query for all users involved in the meeting (that is, as long as the moderator, participants, or record who including the user, we put out those records gave queries), Oh!
