摘要
本論文主要論述的是基于WEB的選課系統的系統維護模塊的設計與實現。
設計本系統的目的是對選課信息進行管理。學生選課系統維護模塊主要完成的是系統管理與維護功能。課題研究過程中，首先對系統管理模塊進行了詳盡的需求分析，經分析得到系統管理模塊主要完成如下的功能：用戶基本信息、選課信息的錄入,查看,修改,刪除等，同時還具有查詢各個模塊的功能，數據備份，數據還原 ，注銷等功能。系統管理模塊是整個系統的指揮中心，保證整個系統在校園網上安全有效地運作。之后根據需求提出了系統管理模塊的總體設計方案，并據此進行了詳細設計和編碼實現。系統使用B/S結構設計和開發，系統的編碼實現基于VS.NET平臺，使用ASP.NET作為開發語言，SQL Server 2000作為數據庫。代碼中通過使用進程中的Session、盡量使用存儲過程和盡量減少數據庫連接的打開時間等手段來提高性能。
論文中對課題的設計和開發進行了完整地論述。系統開發完成后，對課題要求的功能設計出測試用例，進行功能測試，測試結果證明學生選課系統的維護模塊實現了對該模塊的功能需求，完成了課題的主要任務。
關鍵詞：選課系統，系統管理，ASP .NET
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
