摘 要
本论文主要阐述了基于Web技术的英语网络考试系统的设计与实现。在介绍动态网页程序开发和数据访问技术基础上,提出了网络英语考试系统的组成与结构,阐述了系统的设计方案、实现方法以及所采用的开发工具和相关技术,还重点剖析了前台考试部分的程序设计。
本考试系统采用B/S模式开发,不需安装客户端,被授权用户通过浏览器即可登录系统,从而开始正常的考试。
本系统是基于微软公司的Windows 2000操作系统、Internet信息管理器与SQL Server数据库平台构建而成。微软公司产品优异的性能为本系统提供了高效稳定的运行环境,使本系统无论在运行速度、易用性还是在数据吞吐能力方面都表现卓越。
本系统采用了以下技术方案保证考试正常稳定的进行。全面的容错处理使考试作业流程得到有序的控制,对用户的误操作能够进行有效的屏蔽;在考试过程中,禁止考生刷新浏览器,防止考生误操作导致答案丢失;对鼠标右键操作进行限制,保证考试系统用户界面的完整性;另外,系统还提供了考试时间倒计时功能,使考生随时了解考试剩余时间。在考试结束前一分钟和最后10秒种,系统会提醒考生注意保存答案,防止答案丢失。考试到时后,如果考生还未提交试卷,系统将自动交卷,保证考试严肃、公正的进行。

Abstract
The present paper mainly elaborated based on the Web technology English network test system design and the realization. In the introduction dynamic homepage procedure development and in the data accessing technology base, proposed the network English test system composition and the structure, elaborated the system design proposal, the realization method as well as use development kit and correlation technology, but also analyzed the partial links programming with emphasis.
Have an examination system adopt B/S mode development, need to install the customer end originally, authorized users to log in to the system through the browser, thus begin the normal examination.
This system was structured with SQL Server database platform by a Windows 2000 operating system based on Microsoft, Internet information management device. The performance that the products of Microsoft are excellent has offered the high-efficient and steady running environment for this system; make this system no matter at the speed, apt to behave with the sex or in handling capacity of the data remarkably of operation.
This system adopt a great deal of technological scheme is it have an examination normal going on steady to guarantee. Overall fault-tolerant treatment makes having an examination and gets orderly control in procedure of the homework, can carry on the effective shielding to users' mistake operation; In the course of examination, forbid examinees to break the browser, prevent the examinee from operating and causing the answer to lose by mistake; Is it is it limit to go on to operate by right key to mouse, is it have an examination systematic user integrality of interface to guarantee; In addition system offer test time count-down function, make examinee is it have an examination surplus time to understand at any time. In examination one minute and last one second kind before finishing, system will remind examinee pay attention to answer of keeping, prevent the answer from being lost. Examination then, if examinee submit paper yet, system hand in an examination paper automatically, guarantee it is serious to have an examination, just going on.
