摘 要
离散数学在线考试系统旨在实现考试的无纸化管理,基于计算机和网络技术
进行离散数学在线考试系统的使用,既方便校方对考试的管理,也方便了考生,
尤其适合考生分布广,不易集中的远程教育。
基于远程教育的推广和在线考试需求的增加,本文设计并实现了一套离散数
学在线考试系统。本系统实现了系统管理、考生管理、在线考试、在线制作试卷、
控制学生考试、试卷审批等基本功能。系统采用 B/S 开发模式,以 JAVA 作为开
发平台,结合 JSP、JavaScript、Html 等语言,以 Tomcat 为服务器和 MySql 为
后台数据库。整个系统层次结构简单,操作容易,并具备一定的安全性。考生借
助此系统,可以随时随地的进行课程结业考试,同样,老师使用该系统能更高效、
便捷的组织在线考试。

Abstract
The online examination system aims at achieving the paperless examination
management. The online examination system, which bases on computer and network
technology, is convenience for the exam management, but also for the students.
Simultaneously, such a system is absolutely suitable for the students in distance
education who are dispersive and difficult to concentrate on the course.
As the promotion of distance education and the increasing demand of the online
examination, this paper presents the design and implementation of the on-line
examination system. The system implements the following functions: system
management, examinee management, online examinations, online production of the
papers, control examinations and paper processing.The system bases on B/S
development model, using Java as a development platform, which utilizes JSP,
JavaScript, and Html language as well. The web server is Tomcat. Database server is
SQL Server 2005. The system structure is simple, easy and safe. Examinee can exam
at any time by using the system. Simultaneously teachers can use the system to
organize online examination more efficiently and conveniently.
Key words: Online examination system; B/S pattern; SSL
