说明：   随着在校大学生人数的不断增加，教务系统的数据量也不断的上涨。针对学生选课这一环节，本系统从学生网上自主选课以及教师的课程发布两个大方面进行了设计，基本实现了学生的在线信息查询、选课功能以及教师对课程信息发布的管理等功能，另外也初步解决了教师在课程信息发布管理上的权限问题。本程序前台采用Dreamweaver 4.03进行页面制作，后台由SQL Server数据库支持，通过使用ASP语言实现动态网页的效果，达到对数据库的操作以完成使用者的要求。本文中除了有对程序的总体设计、详细设计、功能实现等主体部分外，在这之前还介绍了与网上选课系统相关的信息管理系统、网络编程技术、ASP编程语言、SQL Server数据库服务器等的基本内容及发展情况。   关键字：选课、课程信息发布、权限、SQL Server、ASP
( Abstract：with the development of the enrolling number, the data for daily education is increasing, too. This system is special for the on-line course choosing to design both from the aspect of the student and the teacher. The student can choose the course independently and the teacher can manage the information of the announcing course, also. This system is basically used for the on-line information searching, the course choosing and the announcing course managing. Besides, the power of the teacher has been well controlled. The form is made by Dreamweaver 4.03 , the data base is built by SQL Server and the active website is made by using the ASP language .This paper includes the main designing , the detail designing, the function designing and , before this , some basic knowledge and present development of the programs mentioned above. Keywords：course choosing , announcing the course information , power , SQL Server , ASP)
