一、系统概述

本系统是一款使用Java Swing开发的医院就诊预约系统,面向医院的医务人员和患者使用。

系统功能:

患者管理:添加/编辑/查询/删除患者信息
医生管理:添加/编辑/查询/删除医生信息
科室管理:添加/编辑/查询/删除科室信息
预约登记:患者选择医生和日期进行预约
预约查询:查询已预约记录
预约确认:医生对预约记录进行确认
统计报表:就诊统计报表

二、数据库设计

1. doctor表

• did:医生id,主键
• dname:姓名
• dsex:性别
• dage:年龄
• dtel:电话
• department:科室

用于存储医生基本信息。

2. medical_records表

• id:编号,主键
• pid:病人id,外键关联patient表
• pathogen:病原体

用于存储患者就诊记录。

3. nurse表

• username:用户名,主键
• password:密码

存储护士用户信息。

4. patient表

• pid:病人id,主键
• pname:姓名
• psex:性别
• page:年龄
• ptel:电话

存储病人基本信息。

5. queue表

• visitnumber:就诊号,主键
• did:医生id,外键关联doctor表
• pid:病人id,外键关联patient表
• starttime:开始时间
• endtime:结束时间
• paymoney:支付费用

存储就诊排队信息。

关系:

patient表与medical_records表一对多
queue表与patient表一对多
queue表与doctor表一对多
