项目要求
机房预约系统
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
机房信息固定
内容、代码如下共有七个头文件五个源文件,可装在一个文件中
