In this paper, according to the different needs of different people, I design and develop the student achievement enquiry system to facilitate the use of different types of users .The paper describes the implementation of the student achievement enquiry system based on the .NET framework, the ASP.NET technology and SQL technology. Using the B/S mode, the program implements the main function of the system, and it includes student achievement enquiry, teachers input results, students & teachers leave message and get reply and users management. This paper mainly describes the system architecture design, database design, detailed design and other aspects of system. In database design, it designs and establishes a student card, the user information form, the Senate notice table, the Senate resumed messages, etc .However, the system still has some disadvantage. For example, user interface is designed to further appearance and system can be further expanded.
