一、项目简介
包括管理员和学生两个角色:
管理员关键功能包含个人中心、高校信息管理、学生管理、志愿填报管理、在线留言、系统管理等进行管理。
用户可以对个人中心、修改密码、志愿填报、我的收藏等进行操作。
二、系统设计
2.1软件功能模块设计
系统总体结构图如下所示:

2.2数据库设计
根据系统需求,将“用户、高校、志愿填报、高校信息、学生、配置文件、”等作为实体,它们的局部E-R图,如图4-3所示:

三、系统项目部分截图
3.1前台功能实现
系统首页界面如图5-1所示:

系统注册页面如图5-2所示:

高校信息:在高校信息页面的输入栏中输入省进行查询,可以查看到高校详细信息,并进行填报操作;高校信息页面如图5-3所示:

志愿填报:在志愿填报页面的输入栏中输入省或学校名进行查询志愿填报详细信息,并根据需要进行删除操作;志愿填报页面如图5-5所示:

3.2管理员模块实现

管理员进入主页面,主要功能包括对个人中心、高校信息管理、学生管理、志愿填报管理、在线留言、系统管理等进行操作。管理员主页面如图5-7所示:
