摘 要 随着计算机网络迅速发展，信息资源统计和日常办公也迅速无纸化和网络化。大量数据的搜
集及处理通过网络实现已经非常普遍，且技术已经相当成熟，如国家公务员考试报名系统，学生电
子档案管理系统等。本系统旨在使高校学生选课简单化、方便化和快捷化，抛弃了传统的 ASP 技
术而是采用了 B/S(Browser/Server)架构和 ASP.NET 技术用以实现。系统分三种角色登陆，学生，
教师和管理员都可以在浏览器端完自己的各项工作，且本系统是服务器端执行，故效率较 ASP 网
站有所提高。
关键词 ASP.NET；ACCESS 数据库；选课系统
Abstract: With the rapid development of computer networks, statistics of information resources and the
daily office work are becoming paperless and networking quickly. Large amounts of data collection and
processing through the network is very popular, and the technology is quite mature, such as the National
Civil Service Examination Registration System, student electronic records management systems. The
system is designed to simplify the college students course selection, the convenience and faster technology,
abandoning the traditional ASP technology instead of using the B / S architecture and ASP.NET technology
to achieve. System is divided into three types of landing the role of students, teachers and administrators
can be completed in the browser all the work themselves, and this system is a server-side implementation,
so more efficient than the ASP web site increased.
Key words: ASP.NET Access Database Course Selection System
