前 言
网络商店从前台看是一种特殊的WEB服务器。现代WEB网站的多媒体支持和良好的交互性功能成为建立这种虚拟商店的基础，使得顾客可以像在真实的超级市场一样推着购物车挑选商品，并最后在付款台结账。这也就构成在线图书销售系统软件的三大支柱：商品目录、顾客购物车和付款台。
好的商品目录可以使顾客通过最简单的方式找到其需要的商品，并可以通过文字说明、图像显示、客户评论等充分了解产品各种信息；商品购物车则衔接商店和个人，客户既可以把他喜欢的商品一个个放到购物车里，也可以从购物车中取出，直到最后付款；付款台是网络交易的最终环节，也是关键的环节。
本文主要分6章，主要涉及到以下内容：对有关基础知识的认识，网站系统的设计思想，数据库的设计，功能模块的设计与实现技术等。在线图书销售系统正处于一个重要的发展时期。Web应用系统技术中新概念、新产品的不断推出，同时也给在线图书销售系统提供了新的技术支持。回顾Web应用系统的发展历史，一方面可以了解现状，另一方面也可以更好的认识Web应用系统的发展趋势。
