摘   要

网上拍卖是一种经历长时间考验并留存下来的一种网上交易方式。是以互联网为平台、以竞争价格为核心，建立生产者和消费者之间的交流与互动机制，共同确定价格和数量，从而达到均衡的一种市场经济过程。它具有运行快、方式多、成本低等优点，通过Internet将拍卖活动变成每一位网民都可以加入其中的交易方式。值得注意的是，它给人们带来全新体验以及便利的同时，有许多问题出现在人们的视野，也受到广大群众的的关注。它是否公平、公正、公开，尤其是其可靠性和安全性更是大家关心的问题。这就要求不仅要在系统的设计上做到公平合理，也要在传输上也要做到信息的安全可靠，以构建一个“三公”的交易平台。

本文构建了一个基于Browser/Server模式的网上拍卖系统，为买卖双方搭建了一个公平公开并且安全可靠的交易平台。本文着重论述了系统的模块设计、数据流程和功能实现。其功能包括买家以及卖家的用户注册和登陆、商品搜索、竞价拍卖、买者评价、留言、后台数据库管理、卖家信用度评级等功能。包括如何运用JSP、HTML、JavaScript、JAVA等关键技术建立网上拍卖系统。
