java书店系统项目功能需求：

1、能进行操作用户的注册，修改基本信息，删除和查询。

2、能对图书的基本信息进行增加、删除、修改和查询操作。

3、能填写进货单，一张进货单带有多条具体的进货信息，进货的书籍必须是图书管理里面已经有的；进货的同时修改库存对应书籍的存货量。

4、能填写销售单，一张销售单带有多条具体的销售信息，销售的书籍必须是图书管理里面已经有的，而且销售的数量不能超过当前库存的数量；销售的同时修改库存对应书籍的存货量。

5、可以查看库存的明细，可以按照条件进行查找具体的图书的库存值。

6、权限方面进行简化，做固定的权限控制。把用户按照模块分成不同操作权限的人员，特设一个admin的用户，可以操作全部的功能。

项目基本设计：

★ 架构设计：

整体框架、模块划分

模块划分：用户、图书、进货、销售和库存5个模块

★ 系统功能结构设计：

每个功能模块的具体功能子模块

★ 数据库设计：

项目框架实现：分模块、分层、分包、构建应用程序

核心框架—-实现每个界面的转换
