Abstract
With the development of the enrolling number, the data for daily registry is increasing, too. And always we should goto classroom to enroll. Although this method directly,but result in blindness of the course enrollment and registry data processing of the heavy .In order to reduce the work registry ,and better each student to choose their own favorite subjects .This system is special for the on-line course choosing to design both from the aspect of the student and the teacher. The student can choose the course independently and the teacher can manage the information of the announcing course, also.
This paper gives the basic design idea of the Browser/Server structure based online course elect system by analyzing the characteristic of the Browser/Server structure and combining with the actual public elective courses conditions of our school．It introduces the function module and database design briefly，followed by a discussion on database accessing technology and the active page technology of the course elect system based on ASP.NET and SQL Server 2000．By using this system，students can elect courses online efficiently．This Browser/Server structure system is developed under VS.NET platform in Windows XP operating system, using C# as ASP.NET development language and SQL Server 2000 as the database. This system is of higher security and better performance. The character string, which is used to connecting to the database, can be modified at any time in the file “ web.config”. The string is encoded and encrypted, increasing flexibility of the system and security of the database. In code, making use of stored procedure and minimizing the database opening time to improve performance of the system.
This paper includes the system analysis ,the main designing ,the database designing, the function designing and , before this , some basic knowledge and present development of the programs mentioned above.
