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浏览器来实现极少部分事务逻辑在前端 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BS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BS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管理满足任何授权的考生随时随地考试并迅速获得成绩同时也大大减轻了教师出题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 CS MIS architecture or based web use BS architecture In the exam system of CS 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 BS 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 BS architecture WEB application software is either of CS or BS modes The main disadvantage of the previous mode is the trouble of maintenance and update and thus the charge is higher the BS architecture posed of Browser and Server In this architecture the user interface is just implemented on Browser 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 and BS architecture It has implemented the basic function needed by the student teacher and
