Previous elective method is to use artificial methods to manage file archives, this management approach has many disadvantages: low efficiency, poor security, while over time, will generate a large number of documents and data, which for finding, updating and maintenance of bring a lot of difficulties. With the continuous improvement of science and technology, the puter has access to all areas of human society, and play an increasingly important role. As a part of puter applications and practical management of information technology is absolutely elective, with manual management inparable advantages. For example: to find convenient, high reliability, large memory capacity, security and good, long life and low cost.This paper analyzes the browser / server structure is characterized by bining the actual situation of elective a brief introduction of the system of functional modules and database design, focused on using technology and SQL Server 2005 Developer elective system, access to the database technology and dynamic web production techniques, and give some of the core code can be achieved. Through the system so that students can easily online Online Course on campus. The system is Windows XP system and VS2005 platform is developed using C as the development language, SQL Server 2005 as a database. System has a higher security and better performance. In which the databa
