Students’course selection system
Abstract: This issue discusses the management of students ' course selection system procedures, Through the feasibility analysis, the requirement analysis, the design, the detailed design and analysis of test, so as to explore a development of selecting course system in the WEB environment. The system design based on Web b/s structure and environment. Application development. NET technology, using ASP.NET technology renders Web pages at the front desk, the background is required to use SQL Server 2008 database to develop tables and save them one by one. This system meets the basic needs of Web pages course-selecting system and specific to a different permissions for different permissions management and operation, for example, students can manage their own personal information, course selection information and look theirs curriculum schedule; teacher can view his class schedule and information about students who select his course; administrator can manage all of the above information.
