基于B/S模式的考试信息系统

针对现有考试管理信息系统存在的功能单一、设计不规范、可扩展性弱等问题，提出了考试管理信息系统的结构模型和功能框架．考试过程涉及考务人员、教师、考生三类角色，为确保功能完整和信息更新一致．系统采用基于B／S模式的三层结构：三种角色用户的用户均通过WEB层的浏览器与系统进行信息交互，应用程序全部部署在应用层，数据库数据位于第三层数据库服务器层．介绍了实现系统的关键技术，即验证考生身份所采用的远程采集指纹、照片等信息，考试资源分配流程图和分配原则，以及考试质量分析中的代码复用技术．系统已经完成并用于实践，运行效果较好．

Exam information system based on B/S model

Aiming at exam management,firstly this paper analysed the deficiency in the current exam management system such as singular function,design without standard,weak expansibility,then induced the design principle with the help of the requirements of exam information system with polyfunctionality,excellent general availability and safety property,at last a functional architecture and a new framework model of the exam information system based on B/S model were established.In order to ensure the polyfunctionality and data updating realtime, three structure systems of B/S were designed.There were three roles in exam,i. e,proctor,teacher and examinee.Application programs were all in application lay out and database was arranged in database server.System's six essential functio ns ensured the polyfunctionality and they were exam resource management,test af fair management,examination papers management,test quantity analysis,data query system,authority management and data maintenance management.Meanwhile,key implements based on J2EE were given,including collect examinees' finger print and photo by internet,algorithm flowchart and principle of resource allocation a nd how to accelerate the code's efficiency.It has been successfully implemented at a college and working well there.
