摘要：Web2.0的兴起，掀起了互联网新一轮的网络创业大潮。以用户为导向的新网站建设概念，细分了网站功能和用户群，不仅成功的造就了一大批新生的网站，也极大的方便了上网的人们。但Web2.0以用户为导向的理念，使得新生的网站有了新的特点——高并发，高流量，数据量大，逻辑复杂等，对网站建设也提出了新的要求。
学生选课是教务系统的核心功能之一，其基本要求是根据学生的基本信息，列出所有符合条件的可选课程供学生选择，最终形成学生的选课课表。由于选课时段集中，同时在线人数多，对选课系统的性能要求较高。本课题按照面向对象的思想设计和实现了基于ASP.NET三层体系结构的网上选课系统。并采用常用的优化策略对系统进行优化,使之能满足高并发条件下的学生选课。

Abstract：Web2.0 The rise of the Internet has set off a new round of network entrepreneurs tide. User-oriented concept of building the new site, the site features and sub-users, not only the success of creating a large number of new sites, but also greatly facilitate the access of people. But Web2.0 to the idea of user-oriented, making the new site with new features - with high, high-traffic, large amount of data, logic and complex, building on the site also made new demands.
Academic classes of students is the core function of the system, the basic requirement is based on the students the basic information, list all the eligible optional courses for students to choose the ultimate form of classes students Timetable. As classes on time, the number of on-line at the same time, the selection system of higher performance requirements. The object-oriented issues in accordance with the idea of ASP.NET technology, integrated common measures and the optimization optimize the operation of the relevant data. Designed to adapt to higher classes with students under the conditions of the function.
Elective management school students educational administration is an important component of the work, students of information technology management classes in modern schools human resources development and management of an important means. In introducing the paper on the basis of AsP.NET technology, design and realization of the three-tier system based on ASP.NET structure of the classes online system.
