摘  要：随着社会的快速发展，商品交易的网络化已经很普遍。本设计拟通过在校园里建设一个非商业用途的公益性的交易平台来研究电子商务网站建立所具有的重要的社会意义和参考价值。设计任务核心在于建立一个主要由在校学生介入使用的二手闲置商品交易网站。学生的二手学习资料，生活用品，等一系列毕业在即需要处理的物品，都可在这个交易平台上发布使用。

本软件是基于web的应用，利用HTML、CSS、javascript等技术做前端页面开发，后台语言采用了如今非常热门的PHP语言，后台数据库使用MYSQL设计，为便于实现敏捷开发，采用了目前国内大部分企业都在使用的THINKPHP框架。从而快捷高效地实现本系统的功能，主要包括用户登录注册模块、发布商品模块、编辑商品模块、查看与搜索商品模块、用户个人中心模块，后台管理模块。系统设计过程中，先是建立系统的大致框架结构，在此基础上进行数据库设计，数据库逻辑测试成功后然后就是详细设计阶段，测试阶段，最后形成达到设计要求的可行性系统。66027

ABSTRACT:  With the rapid development of the society, the network of commodity trading is common.. The design of the proposed by on campus established a non - commercial use public trading platform to explore electronic commerce website construction has important social significance and reference value. The design task is to build a second-hand commodity trading website which is mainly used by the students in school..

So quickly and efficiently realize the function of the system, including user login module, the released product module, editing module of goods, check and search module of goods, inpidual user center module, background management module. System design process, first is to establish the system of the general framework of the structure, on the basis of database design, database logical test is successful then is the detailed design stage, testing stage, and finally the formation of meets the design requirements of the feasibility of the system.
