基于Java和DAO设计模式的网上购物系统的实现

Implementation of an Internet shopping system based on Java technology and DAO design pattern

随着网络技术和面向对象技术的发展,面向对象的多层开发已经成为主流。在这里数据库仅仅作为对象持久化的一种工具来使用。本文通过一个具体的网上购物系统详细介绍了DAO设计模式的组成以及如何利用OJB来实现DAO设计模式。

With the development of the network and object - oriented technologies, the N - tier development which is objected - oriented has become the main developing method. Here the database is merely used as an object persistence tool. This paper introduced DAO design pattern in detail by an intemet shopping system. At last the paper implemented the DAO design pattern with OJB.
