2 数据结构
本系统包含用户表、商品表、订单表三个表单，并在数据库中添加一些触发与引索，使用阿里云的RDS-MySQL数据库，本文转载自http://www.biyezuopin.vip/onews.asp?id=15318数据库版本为8.0.16。
2.1 用户表User
1.用户编号：int类型，真动增长，主键，字段名：_id；
2.姓名：varchar类型，非空，字段名：name；
3.用户名：varchar类型，非空，添加唯一引索，不可重复，字段名：uname；
4.密码：varchar类型，非空，字段名：password；
5.身份：varchar类型，非空，默认用户，字段名：role；
6.销售额：decimal类型，非空，默认为0.0，字段名：Sales；
2.2 商品表commodity
1.商品编号：int类型，真动增长，主键，字段名：id；
2.商品条码：varchar类型，非空，添加唯一引索，不可重复，字段名：Barcode；
3.商品名称：varchar类型，非空，字段名：name;
4.生产厂家：varchar类型，字段名：factory；
5.商品类别：varchar类型，字段名：category；
6.商品价格：decimal类型，非空，默认0.0，字段名：price；
7.商品销量：int类型，非空，默认0，字段名：sales；
8.商品库存：int类型，非空，默认0，字段名：sum；
2.3 订单表sales
1.订单编号：int类型，真动增长，主键，字段名：id；
2.订单详情：varchar类型，内容商品名*数量，用|分隔，字段名：val；
3.订单金额：decimal类型，非空，默认为0，字段名：amount；
4.操作编号：int类型，非空，对应用户编号，字段名：user_id；
5.操作姓名：varchar类型，对应用户姓名，字段名：user；
6.订单时间：timestamp类型，非空，自动填写插入时间，自动名：time；
触发：当插入时候，自动更新用户表的销售金额。
3 程序简述与功能
2.1 程序简述
本程序除了完成作业要求外，还美化了用户界面，优化了用户体验，包含了用户表、商品表、订单表三个数据源，并提供了商品管理、用户管理、订单管理、收银台等子系统。本系统可以提供用户检验、权限判断，商品的管理、用户的管理和收银，并将所有可能的异常进行了异常处理。
2.2 实现功能
1.登录验证与在线/权限检验；
2.用户注册；
3.商品管理：包括增删改查，条件筛选，模糊查询，批量修改；
4.收银台：包括添加商品、修改数量、移除商品、计算金额、统计订单；
5.订单管理：包括订单浏览，条件筛选，模糊查询，按时间过滤等；
6.用户管理：包括浏览用户，修改资料，删除用户，修改权限，模糊查询，条件筛选等；
7.补充、添加商品库存；
