摘要:随着我国市场经济的持续深化和现代信息技术的不断发展，电子商务越来越受到人们的重视和欢迎。C2C电子商务网站日渐流行，由此催生了大量的网络商店。网店因其特性与因特网密切相关，由于资金、人员、技术等问题，很多网店经营方式较为粗放，在网店的经营管理中引入进销存管理系统能够减少成本，使网店的管理更加的规范合理。本论文的主要任务是研究并开发一套简易、轻量级的ERP进销存管理系统，以帮助网店降低运营成本，提高经营效率。

　　在基于WEB的应用系统开发上，J2EE平台占有十分显著的地位，它提供了中间层集成框架用来满足无需太多费用而又需要高可用性、高可靠性以及可扩展性的应用需求。本论文采用B/S（Browser/Server）三层体系结构作为进销存管理系统的总体结构，并综合运用J2EE、JSP、JavaScript脚本语言、HTML语言等技术，后台数据库采用MySQL 5.0，基本实现了网店中采购、销售、仓储、财务、客户的管理及信息查询。

已经有很多成熟的软件可以采用，但是这些软件主要是面对大中小型企业的ERP系统。网店作为较小型经营个体，缺乏足够的资金引进软硬件，没有人才和技术运营维护这些大型软件，而且网店经营规模相对较小，也并不需要这些大型ERP系统。此外，网店由于其投入小、入门门槛低，使用者层次差别比较大。鉴于以上原因，本论文将具体阐述开发一套简易、轻量级、易学易用的ERP进销存管理系统，以帮助网店提高经营效率，致力于使网店的管理工作科学化、规范化，降低管理成本，实现管理现代化，扩大市场的竞争优势。
