数学笔记.doc基于WEB的学生综合测评系统的设计与实现
摘要
本文根据学生综合测评系统的特点,采用B/S(浏览器/服务器)的系统设计方案。和SQL Server 2008开发环境,设计并实现了一个学生综合测评系统。主要工作如下:
首先,本文对系统进行了全面的分析,具体包括可行性研究、需求分析、数据流程分析以及系统流程分析。通过对可行性进行研究,得出了系统开发是可行的结论;通过用户的需求分析,了解了综合测评系统应该具有的功能;通过数据流程分析,明白了系统中数据的流向;通过系统流程的分析,得到了系统流程图。
其次,本文阐述了该系统的设计与实现,其包括总体设计、数据库设计及详细设计与实现,通过对系统的总体设计,划分出系统具体的功能模块;通过对数据库的设计,得到了系统的逻辑结构;通过详细设计与实现,实现了系统的各项功能。
最后,本文介绍了该系统测试的方法、步骤及采用的测试用例。经过一系列严格的测试得出的结论是:虽然本系统存在一定的缺陷,但是其各项功能却是较为可靠的。
本系统界面友好,操作简单,比较实用。

ABSTRACT
According to the characteristics of prehensive evaluation system, the essay uses the B/S (Browser/server) system design, chooses and SQL Server 2008 development environment, designs and implements a prehensive evaluation system. The main work is as follows:
First of all, this essay conducts prehensive analysis on the system, including feasibility study, demand analysis, data flow analysis and the system flow analysis. Based on the feasibility study, it draws a conclusion that the system development is feasible. Through analyzing the demands of the users, we understand the function prehensive evaluation system should have. Based on data flow analysis, we know data flow of the system. By analyzing the system flow, we obtain the flow chart of the system.
Secondly, this essay clarifies the design and realization of the system, including the overall design, the database design and the detailed design report and the realization. Through the design of the whole system, we divide it into specific function module of the system. By designing the database, we obtain system logic structure. And through the detailed report and the realization, we realize the functions of the system.
Finally, the essay introduces the method and the progress of testing the system and applies some test examples. Through a series of strict tests, it can be concluded that although this system has certain defects, its function is more reliable.
The system is more practical with a friendly interface and a simple o
