| With rapid development of computer technology and internet, education of high quality requires more efficient management. Therefore, education management system is continuously changing and perfecting.We adopt C/S mode and B/S mode in our system to process large amount of data. The system applies C/S mode as the main mode. it is very simple, convenient and has a high speed. It can improve the efficiency, release the loan of the network, it also has a high safety.The system has a center database server, and each customer visits database through school net. B/S mode is only used on part of moulds, including course-selecting, information announcement, and score enquiry online. Customer can operate by scanner. The B/S mode only needs to program Web application. It is saved on the Web server; only need a standard, easily-used browser. 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. This mode decreases the cost and design circle of the system programming, keeps the safety of the data and the whole system operated immediately, simply, conveniently and has a friendly interaction.The system create safer, more flexible and stable applied program by C# language based on ASP.NET, and the advantage of C# language is experienced which combines two most important computer languages: C++ and Java, furthermore, it has the other new features such as anaphora and index.This article is composed of five sections (chapters).The first section deals with the background of systematic development. With the spring up of INTERNET/INTRANET, especially with further college teaching reforms, the teaching management pattern has transformed from school year to score system. Generally, the school authorities offer a certain quantity of optional courses. Course-selecting is an urgent requirement in educational administration management. Therefore selecting courses online is the tendency of necessity. As a result, we have got the goal and premise of development, at the same time, the structure of this paper is also depicted. The second section introduces related concepts and technology used in this system, as well as the development and designing tools (environment) applied. Of which UML is introduced. UML is the standard language of the software blueprint, and it offers a set of concepts and graph representation for the description of software models, as well as language expansion system and object restraint language. Software development people can use UML language to establish visible system models, make statement and establish software document for complex software system. UML supports object- oriented technology and methods, expresses object-oriented concepts accurately and conveniently, and embodies object-oriented analysis and designing styles. It also briefly introduces ASP. NET, which is a kind of server technology and it combines with various Web elements together. ASP. NET is a union Web development platform, and it offers various services necessary to generate a complete Web application program. At the same time, it supplies a kind of new programming model and structure which used to generate a safer, more flexible and stable applying program. ASP. NET is a compiled applying program which is based on .NET environment, and may be created by using any .NET compatible language. C# language is also discussed in this section. C# language is a kind of new programming language developed by Microsoft company'. C# language represents a new stage of programming language development, and it has inherited the advantages of C++ and Java, the two most important computer languages in the world, and has some new features such as anaphora and index. Meanwhile, with .Net as its powerful platform, C# language has been widely used in Windows graph user interface, ASP. NET Web application, XML Web Service and ADO. NET database. This section also discusses XML technology, one of whose advantages is that it permits any organization or ind...
