基于java实现的计算机考试系统
摘要
无纸化考试系统是现代教育的重要标志,让考试的结果更加的合理、公正、公平,也可以节约人力成本。高校在线考试系统,常用客户机/服务器(C/S)型的MIS型架构,或基于Web使用浏览器/服务器(B/S)的架构。C/S架构的在线考试系统,试题存放在远程服务器上,客户端安装考试应用程序和数据库客户机配置,每次考试时需对客户端进行安装、配置。而采用B/S架构的考试系统,通过与B/S结构的数据库管理系统结合可实现瘦客户机,系统维护仅需在服务器端进行。故开发了基于B/S的在线考试系统。网络应用软件运行的模式主要有两类:C/S和B/S模式。前者主要的缺点是维护、升级相对比较麻烦,费用也比较高;B/S(Browser/Server)结构即浏览器和服务器结构。在这种结构下,用户工作界面是通过辑在前端(Browser)实现,主要事务逻辑在服务器端(Server)实现。这样大大简化了客户端电脑载荷,减轻了系统维护与升级的成本和工作量,降低了用户的总体成本。
本论文的内容就是设计一个基于java的B/S结构的计算机考试系统,可以基本实现学生、教师以及管理员所需要的功能。在这个B/S结构的设计中,学生通过计算机网络登入系统,实时提交解答。系统能保存结果,供教师披阅,并能自动根据条件对客观题进行判分,还能对分数进行统计、管理,协助教师找出教学中存在的问题,满足任何授权的考生随时随地考试并迅速获得成绩的需求,同时也大大减轻了教师出题、监考和判卷等繁重的工作量。

Abstract
Paperless exam is an important symbol of modern education for this kind of exam make the result more reasonable, more just, and release human resource. The online exam system of university, usually uses the C/S MIS architecture, or based web use B/S architecture. In the exam system of C/S architecture, where the papers are stored in the remote Server and the Client must set up the exam application and configure the database, we must set up and configure the Client every time when do exam. However, the exam system using the B/S architecture can implement thin Client bining the Management Information System. As system maintenance is only necessary at the sever end, our developed exam system is based on B/S architecture. WEB application software is either of C/S or B/S modes. The main disadvantage of the previous mode is the trouble of maintenance and update, and thus the charge is higher; the B/S architecture posed of Browser and Server. In this architecture, the user interface is just implemented on , a little part of the transactions is implemented in Browser, and the main part of transactions is implemented in Server. So the load of Client is reduced, and thus reduce the cost of maintenance and update, so as the whole cost.
This graduate project is about the exam system based on java a
