项目编号：BS-QD-002
主要需求：
- 学生信息录入、修改、删除、查询
- 宿舍管理评分
- 学生早起率、懒床率
- 学生宿舍打扫频率
- 学生晚归情况
- 楼层管理
考虑到实用性，该系统需要拆分为两大子系统，一个是学生端系统，一个是后台管理端系统。学生端系统主要提供给学生使用，负责一些宿舍记录及个人信息记录的基本操作；后台管理模块则是主要负责对所有学生信息的整理，提供宿舍管理、楼层管理、数据查看等权限，提供给宿舍管理员使用的。
学生登陆
学生系统拥有以下功能：
- 创建账户
- 分配宿舍
- 填写个人信息
- 修改个人信息
- 起床打卡（用于统计懒床率）
- 归宿登记（用于统计晚归情况）
- 打扫记录（用于统计宿舍打扫频率）
- 查看宿日常数据
管理员登陆
管理系统拥有以下功能：
- 楼层管理
- 宿舍评价
- 宿舍信息管理
- 学生信息查看
- 保洁人员管理
- 统计学生早起率
- 统计学生宿舍打扫频率
- 统计学生晚归
超级管理员在享有上述管理员同等权限的同时额外拥有如下功能：
- 创建管理员
- 创建宿舍楼
- 为宿舍楼分配管理员
- 为宿舍楼分配保洁人员
前端：
- Vue 作为基础框架
- vue-router 控制路由（hash 模式）
- vuex 状态管理
- axios 接入数据
- Vue-element-admin 作为基础框架
后台（Nodejs）：
- Koa 作为基础框架
- koa-router —— 服务端路由控制
- koa-static —— 读取静态文件
- koa-jwt —— JWT 登录校验
- koa-body —— http body 数据处理
- koa-compress —— Gzip 压缩
- koa-cors —— CORS 解决跨域问题
- sequelize —— ORM
数据库：
- MySQL
数据库设计一览：
下面展示一下系统的部分功能：
仪表盘概揽：选择不同的宿舍楼查看相关信息
管理员管理：
宿舍楼管理
楼层管理
宿舍信息
宿舍入住学生信息
查看学生起床记录
查看学生归宿信息
查看学生宿舍打扫信息
查看个人信息
学生注册
注册后登陆系统
入住宿舍
起床打卡
归宿记录
打扫记录
