ABSTRACT

According to the characteristics of student comprehensive evaluation system,the essay uses the B/S(Browser/server) system design, chooses ASP.NET and SQLServer 2008 development environment, designs and implements a studentcomprehensive evaluation system.The main work is as fol lows:

First of al l, this essay conducts a comprehensive analysis on the system,including feasibi l ity study, demand analysis, data flow analysis and the systemflow analysis.Based on the feasibi l itystudy, it draws a conclusion that the systemdevelopment is feasible. Through analyzing the demands of the users, weunderstand the function the comprehensive evaluation system should have.Based on data flow analysis,we know data flow of the system. By analyzing thesystem flow,we obtain the flow chart of the system.

Secondly, this essayclarifiesthe design and real ization of the system, includingthe overal l design, the database design and the detai led design report and thereal ization. Through the design of the whole system,we divide it into specificfunction module of the system. By designing the database,we obtain systemlogic structure.And through the detai led report and the real ization,we real izethe functions of the system.

Final ly, the essay introducesthe method and the progress of testing the systemand appl ies some test examples. Through a series of strict tests, it can beconcluded that although this system has certain defects, its function is morerel iable.

The system is more practical with a friendly interface and a simple operation.

Keywords: Evaluation System,ASP.NET,SQL Server 2008
