| Teaching activities are, in universities or institutes, one of the main functions and an important standard of high school management level. In recent years, the popularizing and develop at full speed of computer network, has offered the strong information processing platform of the function, has brought deep influence on work and all respects, such as daily life, etc…The popularizations of network offer the convenience to teaching management system too, create an integrated environment of handling official-business. Three old colleges join together, the number of student increase, the scale of the college become more and more large, all of that case a lot of problems to the college's teaching activities. In order to improve the level of the institute's teaching management, I design the Teaching Activities System.The reason why we adopt C/S mode and B/S mode in our system is that to adapt to precede large amount of data and make more student to use. The main partition of the system is special to the professional person working in the teaching office. The main mode of the system is C/S mode, for it is very simple, convenience and has a high speed. It can improve the efficiency, release the loan of the network, it also has a high safety. The teacher or student of different majors except the professional person, also need to access the data. To them, the better method is to adopt B/S mode. The B/S mode only needs to program Web application (it is not necessary to design client program). It is saved on the Web server; only need a standard, easy-use browser. It is not necessary to set up client application to every user, so it is not need to make some special configuration and setup. All the work can be done on the Web server instead of doing on the client machine. By doing that, it samples our job and decreases the cost. All of the reasons just refer to decide that the system's mode is mixed C/S mode and B/S mode. It decreases the cost and design circle of the system programming, breaks through the old system's limitation, keeps the safety of the data and the whole system operated immediately, simply, conveniently and has a friendly interface.Microsoft.NET is the next generation development platform issued by Microsoft Co. in June 2000. In March 2003 the formal Chinese edition of .NET was launched, which represents a new revolution of software technology. In brief, .NET is a strategy of Microsoft. It regards the supply of the software as a service to treat. Include .NET Framework, tool and service used for establishing, running the new-type service on .NET platform. The class-library supplied by the .NET framework constructs ASP.NET. It is not only the master of the common language's running environment, but also a whole structure for web site and Internet objects. The web form's mode supplied by ASP.NET makes that create, manage and config web application become easier. The programmer can directly use ASP.NET to create controls used on servers. The programmer can use ASP.NET web service function to design simple logical application, and can use the base structure of ASP.NET to provide service through SOAP. Base on ASP.NET and adopt the adaptable design mode, you can get the reasonable structure and easy maintain web application solution.C# is a new programming language issued by Microsoft company inherited from C++ language. In the past 20 years, C++ is the most popular used to program business software. C++ provide programmer a lot of flexible methods to control the essential function, but it also need long period to program. For instance, point operation often cause some unsafe effects, memory recycle need the operation of programmer and so on. It means that it is hard to use C++ to program than other computer languages in common sense. C# not only has the strong ability and good flexibility equals to C and C++ language, but also has rapid-program attribute equals to visual basic, and it has been designed special to .NET framework. It can construct from essential system to high-leve...
