文档介绍：摘要
在当今信息时代,计算机技术与网络技术越来越广地应用于各个领域,改变着人们的学习、工作、生活乃至思维方式,也引起了教育领域的重大变革。将计算机与网络技术应用于现代教育中,是现代教育发展的需要,也是改革教育模式,提高学校教学效果和教学效率、提高科研和管理水平的必要手段。
本系统是在Windows 7下,以IIS( Information Server)网络信息服务为应用服务器,+SQL server 2008等工具开发的网络考试系统。系统采用WEB技术实现,WEB技术超越了传统的“客户机/服务器”的两层结构,采用的是三层体系(B/S)结构:用户端/服务器端/数据库,上完成在线考试及自动评分。
本文首先介绍了网络考试系统的背景、发展现状,然后介绍了网络考试系统所需要的相关知识和技术支持。针对课题的需求进行了需求分析,详细的分析了系统功能要求,并进行合理的功能划分。在面向对象分析的基础之上,对系统进行界面设计、后台设计和数据库设计,给出了总体系统设计、子系统设计的模块及流程图,还有数据库逻辑设计E-R图,物理设计的结构图。设计之后描述了系统的实现技术和最终实现效果,并结合系统不足之处和考试系统的发展方向对系统的改进提出了建议。

Abstract
In today's information age, computer technology work technology are used in various fields more and more widely, changing the way people learn、 work、live, even the ways of thinking, and also it causes major changes in the field of education. puter technology work technology to modern education ,is not only the need of modern education ,but also the necessary means of the reform of the education model, the improvement of School teaching effectiveness and teaching efficiency and the improvement of research and management level.
This system is work Examination System developed by , SQL server 2008 and so on In Windows7 environment with IIS as the application server. The system is achieved by web technology, web technology surpasses the traditional "client / server" two layer system structure by using the three layer system structure ( B/S ):client / server / database, and online test and automatic scoring can pleted In the LAN and on the .
This paper first introduces the background, development status work examination system, then the related knowledge and technical support it needs. According to the demand for the subject, demand analysis, detailed analysis of system functional requirements and reasonable division of functions are done, On the basis of object-oriented analysis, Interface design, background design and database design pleted, besides, module and flow charts of the whole system and subsystem,
