一、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
·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
