Design and Implementation of Learning System
based on the .NET Framework
Abstract
This paper describes the design and implementation of Learning System based on VS.NET.
First, at the beginning part ,this paper presents the technology that the System uses. Compared with the VS.NET2003 develop environment, this Learning System which is based on VS.NET2003 has many new functions. I try my best to use the new technology, including Master Pages , Data Source Controls , Data Controls , Role Management , Login Controls and so on.
Second, this paper describes the design process of the system in detail. It describes the decision of system structure. Trough the comparison of each structure, the Three-tier Structure is adopted by the Learning System as it has more advantages. Then the paper presents the 5 modules of the system according to the requirement analysis report, including Students’ individual information management, resource download, homework submission, simple bbs and test online and describes the implementation flow of each module in detail. In addition, this paper describes the design and structure of the database for the Learning System.
Finally, this paper describes the implementation of the system and each class libraries in detail and introduces the code of each part according to the Three-tier Structure.
