摘要
本论文主要论述的是基于WEB的选课系统的系统维护模块的设计与实现。
设计本系统的目的是对选课信息进行管理。学生选课系统维护模块主要完成的是系统管理与维护功能。课题研究过程中，首先对系统管理模块进行了详尽的需求分析，经分析得到系统管理模块主要完成如下的功能：用户基本信息、选课信息的录入,查看,修改,删除等，同时还具有查询各个模块的功能，数据备份，数据还原 ，注销等功能。系统管理模块是整个系统的指挥中心，保证整个系统在校园网上安全有效地运作。之后根据需求提出了系统管理模块的总体设计方案，并据此进行了详细设计和编码实现。系统使用B/S结构设计和开发，系统的编码实现基于VS.NET平台，使用ASP.NET作为开发语言，SQL Server 2000作为数据库。代码中通过使用进程中的Session、尽量使用存储过程和尽量减少数据库连接的打开时间等手段来提高性能。
论文中对课题的设计和开发进行了完整地论述。系统开发完成后，对课题要求的功能设计出测试用例，进行功能测试，测试结果证明学生选课系统的维护模块实现了对该模块的功能需求，完成了课题的主要任务。

Abstract
The topic is mainly to comment designment and implementation of the maintenance module of the Web-based Course Selection System.
The purpose of Course Selection System is to manage the course selection information on computer. Research process, the first system management module for a detailed needs analysis. Upon analysis of system management module to be completed the following functions : basic user information in the Course Selection logging information, the following changes. delete, inquiry also has the function of each module, backup data, restore data, the write-off and other functions. The entire system is the command module management system to ensure that the entire campus network safe and effective transport system to do. After a demand management module design program, and thus achieve a detailed design and coding. The system use the Structure of B/S, using VS.NET as the development language and SQL Server 2000 as database. Session code through the use of the process. Make full use of the process and minimize storage time open database connectivity to improve performance.
The design and development of a thesis topic for a complete exposition. System development is completed, subject to the requirements of the functional test case design and the functionality, Test results show that the system to safeguard optional module of the functional requirements of this module, and complete the main task.
Key words : course selection system, management modules,ASP.NET
