项目介绍
在线考试的需求和管理上的不断提升，在线考试管理的潜力将无限扩大，在线考试系统在业界被广泛关注，本系统及对此进行总体分析，将在线考试信息管理的发展提供参考。在线考试系统对高校有着明显的带动效应，对管理帮助更大。
本系统主要包括管理员，学生和教师三个角色组成；主要包括：首页，个人中心，学生管理，教师管理，课程分类管理，课程信息管理，在线考试管理，试题管理，习题管理，考试管理等功能的管理系统。
开发环境
开发语言：Java
框架：springboot
JDK版本：JDK1.8
服务器：tomcat7
数据库：mysql 5.7 （一定要5.7版本）
数据库工具：Navicat11
开发软件：eclipse/myeclipse/idea
Maven包：Maven3.3.9
浏览器：谷歌浏览器
功能结构
为了更好的去理清本系统整体思路，对该系统以结构图的形式表达出来，设计实现该在线考试系统的功能结构图如下所示：
数据库设计
数据库E/R图
ER图是由实体及其关系构成的图，通过E/R图可以清楚地描述系统涉及到的实体之间的相互关系。在系统中对一些主要的几个关键实体如下图：
(1)课程信息E/R图如下所示：文章来源：https://www.toymoban.com/news/detail-473062.html
(2)在线考试E/R图如下所示：文章来源地址https://www.toymoban.com/news/detail-473062.html
