前言:
互联网的普及给人们带来的便利不需多说。因此如果把题库及试卷管理系统与互联网结合起来,利用My Eclipse编程软件建设题库及试卷管理系统,实现题库及试卷管理系统的网络化。则对于进一步提高教学发展定能起到不少的促进作用。
题库及试卷管理系统能够通过互联网得到广泛的、全面的宣传,让尽可能多的学校了解和熟知学校的题库及试卷管理系统服务等,不仅为学校提供了服务,而且也推广了自己,让更多的学生了解自己。对于学校而言,若拥有自己的题库及试卷管理系统,通过题库及试卷管理系统让学校的宣传、营销提上一个新台阶,同时提升了学校形象。
根据本系统的研究现状和发展趋势,系统从需求分析、结构设计、数据库设计,在到系统实现,分别为前端实现和后端实现。论文内容从系统描述、系统分析、系统设计、系统实现、系统测试来阐述系统的开发过程。本系统力求结合实际找出一种切实可行的开发方案,经过反复研究和学习,借助My Eclipse编程软件、SSM技术、MySQL数据库和Tomcat服务器来完成系统的所有功能,最后进行系统测试,来检测系统的权限和漏洞,从而将系统完善,达到符合标准。
一,项目简介
本项目主要实现SSM开发框架实现在线考试管理系统,采用前后端分离的方式开发实现,基于接口实现前后端开发对接,后端服务系统主要实现的管理功能有:试题管理、试卷管理、考试管理、用户管理、数据字典管理、系统设置管理。前端用户服务实现的功能有:试题练习、在线考试、会员中心、统计知识掌握情况、统计分析各种考试数据等功能。整体功能比较强大,也比较完整。
根据前面的各项设计分析,按照系统开发的基本理念对系统进行分解,从模块上主要可分为用户模块和管理员模块。
用户模块只要是让普通用户使用,包括题库及试卷管理,成绩查询等功能,管理员模块只要是让管理员使用,包括学生信息管理、教师信息管理、试卷管理等功能,可以对数据进行添加、删除、修改及查询等操作。
系统总体功能结构图如下图所示。
