Java之------单机版书店管理系统(设计思想和设计模式系列四)图书模块

书店管理系统

书店管理系统可以说是设计模式及设计思想的一个比较经典的例子。

本系列将分为多个部分讲述此输电管理系统。

书店管理系统将分为：用户、图书、进货、销售和库存五个模块，另外还有公共包、工具包和登录包，另外还有一个框架。

对于分层设计，都是表现层可以调用逻辑层，逻辑层调用数据层，数据层调用工具和公共包，方向不可打乱，必须严格按照这种模式。

本篇将做图书模块。

注：本篇需要使用到的框架在本系列二的用户模块：

同系列有：

系列一(概述)：点击打开链接

系列二(用户)：点击打开链接

系列三(工具包和公共类)：点击打开链接

系列五(进货)：点击打开链接

系列六(销售)：点击打开链接

系列七(库存)：点击打开链接

系列八(登录)：点击打开链接

和用户模块相同的，图书模块分成了数据层、逻辑层、表现层和值对象层。
