论文从系统的研究意义，需求分析，总体设计，具体实现这几个角度对系统的开发过程进行介绍，重点针对需求分析和总体设计进行详细介绍，同时并对该系统所采用的开发工具及技术进行简单的介绍。

系统是利用ASP.NET和SQL Server 2000数据库开发的Web 应用程序。主要针对学生、老师、管理员三种不同用户的需求进行设计，最终实现毕业设计选题网上完成。系统使用起来操作简便快捷，具有管理员发布信息、管理用户、设置系统，学生选择课题、修改个人信息，教师添加课题、确定选题等基本功能。对减轻学生、老师负担，提高选题工作效率，都有显著效果。

The paper introduce the system from the three aspects content：Significance of study，Demand analysis，System design，Concrete realization。Detailed introducing the most important aspects are demand analysis and system design。And the same time，introducing the development tool and technology using by current system.

The system developed web application using ASP.NET technology and SQL Server 2000 database. The system designed for students，teachers and system administrator，and complete the system Administrator can publishe information and user Management。The student can selecte topics and changepersonal information。The teacher can add topics and ensure the selecting。It has

Made notable results to reduce efficiency of topics of the students and teachers，and enhance the Efficiency to select topic.
