本文主要是介绍JSP课设:学校招生系统(附源码+调试),希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
Java web学校招生系统
Java web学校招生系统功能概述
(1)登录模块:学校招生系统提供管理员和考生两者登录角色,分别对应不同的功能,登录信息存储在数据库中。
(2)前台浏览:学校招生系统提供一个官网界面,为所有用户(包括游客)提供首页浏览、师资队伍、专业简介、校园风采等信息浏览界面。
(3)考生模块:个人中心(修改密码、个人信息)、招生计划管理、录取管理。
(4)管理者模块:个人中心(修改密码、个人信息)、考生管理、师资队伍管理、院系分布管理、专业简介管理、招生计划管理、考生录取管理、系统管理(校园风采、咨询回复、轮播图管理)
