基于asp.net的网上购物系统
 

摘要：本论文描述了网上购物的发展状况、以及开发网上购物系统的意义，然后介绍了开发该网站的工具——.NET 技术在网络编程中的特点和优势。本论文以一个网上购物系统作为解决方案的背景，详细论述了本系统开发的需求分析、概要设计、详细设计、测试与系统使用说明，构成了一个完整的网上购物系统的解决方案。本系统的开发采用了基于B/S结构的设计模式；运用ASP.NET 2.0的三层架构思想(表示层，业务逻辑层，数据访问层)来设计网站的总体架构；在此过程中运用了抽象工厂模式来动态加载程序集；在实现技术上，利用ASP.NET 来构建本网站的程序结构和用户界面；利用SQL Server 2005数据库建立后端数据源；利用ADO.NET 技术实现网站中对数据库的安全连接和访问，系统的可移植性高且具有良好的业务扩展性。

A Web shopping system based on asp.net

Abstract: This paper first describes the concept of e-commerce, development and the development of the significance of e-commerce, and then introduced the development of the sites tools ——.NET technology in the network programming in the characteristics and advantages. This paper to a virtual e-commerce sites for the solution of the background, discussed in detail all parts of the system the intrinsic link between the end under the intrinsic link them organically combine together to form a complete e-commerce solutions. System design chosen B/S model framework for the design of the ASP.NET 2.0 by the three tiers of thinking in this process(UI,BLL,DAL), use the abstract factory pattern to dynamically loaded assembly in the realization of technology, use of ASP.NET Construction of the sites program structure and user interface; using SQL Server database back-end data sources to establish the use of ADO.NET technology site in the database and access a secure connection, the system can be transplanted high and has a good business scalability.
Key words: e-commerce sites; B/S model; three-tier system; abstract factory; ADO.NET; ASP.NET
