C++ 【第四篇】综合实战之机房预约系统

机房预约系统

 

一 项目需求

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

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

3 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
