前台登陆：
本系统用户分为三大类：管理员学生家长和老师。
为这三大类用户提供他们各自的功能：
管理员：校内公告发布、申请公告发布到网站、申请新闻发布到网站、校内新闻、登录及权限验证、注册申请、密码找回、管理本校事务。申请家长身份，维护学生——家长关系（申请新的学生与家长关系，取消学生与家长关系）。消息推送。
老师（按不同的身份权限）：登录及权限验证、留言、发布问卷调查、布置作业、考试管理、学籍管理。申请家长身份，维护学生——家长关系（申请新的学生与家长关系，取消学生与家长关系）。消息推送。
学生家长：登录及权限验证、注册申请、密码找回。维护学生——家长关系（申请新的学生与家长关系，取消学生与家长关系）。查看学生作业。即时聊天功能（类似qq群一样）
为实现各用户的功能系统需提供的功能：
网站首页及栏目设置：网站介绍、最近动态、公告、网站新闻、用户登录入口、注册入口、密码找回功能入口。
与用户身份相匹配的个人登录后的功能界面入口：学校用户及学生家长能看到本学校内的公告和校内新闻；与个人权限相匹配的各功能入口。
用户注册及密码找回功能、登录及权限验证功能。
网站页面展示模块：网站介绍、最近动态、学校注册情况、公告、网站新闻、用户登录入口、密码找回功能入口、注册入口。
鉴权及功能入口展示模块：学校用户及学生家长能看到本学校内的公告和校内新闻；与个人权限相匹配的各功能入口。
后台:
系统管理模块：用户帐户管理、权限管理、网站介绍发布、最近动态发布、审核用户注册申请、新闻公告审核、发布系统公告、发布网站新闻。校内新闻管理、申请新闻发布到网站；帐户管理（注册老师用户，为老师用户指定身份角色，激活、禁用帐户）；学科年级信息维护、学校班级信息维护、学科信息维护；学校信息维护。
老师应用模块（按不同的身份权限）：沟通交流、布置作业、考试管理、学籍管理（录入本班学生信息、分班、学生升、留级、毕业）、个人信息维护。申请家长身份，维护学生——家长关系（申请新的学生与家长关系，取消学生与家长关系）。考虑利用手机进行短信推送信息。
学生家长应用模块：沟通交流、作业下载。维护学生——家长关系（申请新的学生与家长关系，取消学生与家长关系）
