【摘要】 拍卖是出卖者通过公开叫价的方式，将物品卖给出价最高的购买者的一种交易形式。随着Internet的普及，互联网以一种巨大变革力影响着商务关系领域。计算机网络为商务活动开辟了新的空间，提供了新的手段，同时为公司业务发展赋予了更多的机会，成为现代商务的潮流。网上拍卖是建立在电子网络技术上的一种全新的电子商务模式，即拍卖交易的中介——拍卖市场成了一个网站，拍卖师的职责由网站的程序来完成。这种交易模式大大提高了效率，降低了交易成本，使得小额商品也能够进行拍卖。本文介绍了用ASP和DELPHI等工具建立一个电子商务拍卖网站。该设计遵循了软件工程中软件生命周期法(瀑布模型)；按照软件分析、软件设计、软件编码、和软件维护等过程，系统分为定义系统目标、可行性分析、需求分析、概要设计、详细设计、软件编码、软件测试、软件维护等九个阶段。并将面对用户的WEB界面采用B／S结构和对于后台数据挖掘的管理逻辑层采用C／S结构。在本文第三部分的过程论述中，采用了结构化设计方法，采用了数据流程图(DFD)，数据字典、程序流程图等工具清晰的展示整个设计开发过程，保证了系统的健壮性，可维护性，可扩充性。建立后的网站是一个动态、交互式、具有在线拍卖、商品提供、系统管理等功能的CTOC商务拍卖网站。更多还原

【Abstract】 Auction is a kind of transaction method of selling merchandise to the persons who can bid the highest price. With popularization of Internet, it brings one anew reform in the field of business relationship. Computer network has opened up the new area for the commercial activity, has offered the new means, and gave more chances for company’s business development at the same time. E-commerce becomes the trends of the modern commercial affair. Auction in the Web is a new e-commerce model which the salesroom becomes a website and auctioneer becomes a computer program. The transaction model upgrades efficiency and reduces the transaction cost which can make small sum transaction take place. The thesis expounds how to build an E-Business Auction web site by use of software tools such as ASP, DELPHI and so on. The design keeps to the classic life cycle of software engineering (waterfall model). According to software analysis, software design, software code and software maintenance, the design is divided into nine processes such as define systematic goal, feasibility analysis, demand analysis, outline design, design, software code, software test in detail, software maintain.In the web interface of user, we adopt B/S structure. And we adopt C/S to backstage supporter management logic layer that needs data mining. Course of the third of expounding the fact, adopt the structure design method in this text, use data flow chart( DFD), data dictionary, procedure flow chart, etc. tool to clear show upgrade the course. The ones that have guaranteed the system are stalwart, the maintainability, and expandability. The main process is in the three part which descriptions the analysis and design. In that part we use a structured system develop methodology -the structure analysis and structure design. We use a lot of method such as data flow diagram and data dictionary to describe the process of building the system.The built web site is a dynamic and interactive CTOC Business Auction website that has functions of auction online, commodities supply and system management.更多还原
