摘    要
随着互联网的迅速的发展,基于互联网的各种应用日益受到人们的重视,基于Web的网上考试系统在这种形势下应运而生,它是伴随着网络技术和数据库技术而逐渐发展起来的。网上考试系统是现行校园教育软件研究的热点之一，如何能科学有效的开展各项网上考试工作，是当前各个学校非常关心的问题。不少学校在利用校园网实现信息与数据的管理、共享，实现高效实时的无纸办公等方面普遍落后。因此提高校园网的利用率，加快学校信息化管理的进程，是一件有着重要意义的研发工作。
本文分析了一般网上考试系统的基本需求，开发了一个采用浏览器／服务器结构的网上考试系统。本系统在Microsoft windows XP操作系统平台下开发，服务器端使用基于VBScript语言的asp作为服务器的服务框架，后台数据库为MS SQL，在浏览器端使用java script技术。现阶段虽只实现了试卷的客观题部分，但已具有试题（卷）录入、修改、添加和删除，成绩的查询和统计，自动评分以及在线考试等重要功能。

The Design and Realization of Network Examination and Assessment System
Abstract
With the rapid development of Internet, all kinds of applications which base on Internet are attended by people gradually, and the online examination system based on Web, and developed gradually with the computer network technology and database technology come into being in this condition. Online examination system is one of the hottest education software in present campuses, and how to develop online examinations work scientifically and effectively has became the most concerned in all the schools. Many schools are out of date in using campus network to manage and share the information data, and realize highly effective paperless office work. Thus, it is a very important research and development work to improve the utilization rate of campus network and quicken information management at school.
The thesis analyzes the basic needs about the general online examination system, which has been developed by using browser / server. The system is developed under the platform of Microsoft windows XP operating system, and the usage of server terminal is based on asp of the VBScript language as the sever framework. The backstage database is MS SQL, and java script technology is used in the browser-side. At the present, although the paper has just been achieved the objective items, it could be functioned with input, revision, addition and deletion of items, and marks inquiries and statistics, auto-scoring and test online etc.
