黑马：机房预约系统（282~314）

1、机房预约系统需求

1.1 系统简介
学校现有几个规格不同的机房，由于使用时经常出现"撞车"现象,现开发一套机房预约系统，解决这一问题。

1.2 身份简介
分别有三种身份使用该程序

学生代表：申请使用机房
教师：审核学生的预约申请
管理员：给学生、教师创建账号

1.3 机房简介
机房总共有3间

1号机房 — 最大容量20人
2号机房 — 最多容量50人
3号机房 — 最多容量100人

1.4 申请简介
申请的订单每周由管理员负责清空。
学生可以预约未来一周内的机房使用，预约的日期为周一至周五，预约时需要选择预约时段（上午、下午）
教师来审核预约，依据实际情况审核预约通过或者不通过

1.5 系统具体需求
首先进入登录界面，可选登录身份有：
        学生代表
        老师
        管理员
        退出

每个身份都需要进行验证后，进入子菜单
        学生需要输入 ：学号、姓名、登录密码
        老师需要输入：职工号、姓名、登录密码
        管理员需要输入：管理员姓名、登录密码

学生具体功能：
        申请预约 — 预约机房
        查看自身的预约 — 查看自己的预约状态
        查看所有预约 — 查看全部预约信息以及预约状态
        取消预约 — 取消自身的预约，预约成功或审核中的预约均可取消
        注销登录 — 退出登录

教师具体功能
        查看所有预约 — 查看全部预约信息以及预约状态
        审核预约 — 对学生的预约进行审核
        注销登录 — 退出登录

管理员具体功能
        添加账号 — 添加学生或教师的账号，需要检测学生编号或教师职工号是否重复
        查看账号 — 可以选择查看学生或教师的全部信息
        查看机房 — 查看所有机房的信息
        清空预约 — 清空所有预约记录
        注销登录 — 退出登录
