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.
