摘  要：在internet飞速发展的今天，互联网成为人们快速获取、发布和传递信息的重要渠道，它在人们政治、经济、生活等各个方面发挥着重要的作用。Internet上发布信息主要是通过网站来实现的，获取信息也是要在Internet“海洋”中按照一定的检索方式将所需要的信息从网站上下载下来。因此网上购物系统应运而生，网上购物弥补了传统购物的一些局限性，成为传统购物的补充。通过网上购物，无论你在哪里都可以轻松地买到心仪的物品，只要那里有一台接入了Internet的电脑，通过网上购物可以很清楚的了解各个商品的信息，从而对它们进行比较，最后买到自己称心的物品。
论文首先介绍了网上购物系统的现状及开发背景，然后对系统的研发进行了详细的分析，论述了系统需求和设计方案，较详细的论述了系统的详细设计和实现。最后，对网上购物系统前台应用软件测试进行了简单的介绍。
系统主要为用户提供了会员注册，购物车，商品搜索，用户资料修改等功能，在设计方面, 采用java语言来编写，后台数据库选用SQL Server2000数据库。通过建立数据源，eclipse与后台的数据库连接来运行。

ABSTRACT：Today  as the development of the Internet growing faster, the Internet became the most important information channel for people aquiring, releasing and exchanging informations, which concerning the political, economic, and other aspects of life plays an important role. Publishing information on the Internet is mainly achieved through the website, access acquiring information is also on the Internet "sea",  by certain ways of searching informations,and then downloading from the site.

In the beginning of my essay, I introduced the situation and development background of online shopping system. And then I have carried on detailed analysis to the system’s research and development, elaborated the system’s requirements and the design proposal, which has detailed elaborating the system’s detailed design and realized. At the last, I have a simple introduction to the on-line shopping system’s onstage application software test.
The system has mainly provided the member registration, the shopping bookmark, the commodities searching, user material revision, etc. In the design aspect, I adopted java language, and SQL Server2000 used as database, through the establishment of data sources, eclipse and the database at the backgroud’s connection used to run the system.
