设计总说明

设计总说明

随着市场经济体制进一步完善，推进经济增长方式转变和结构调整的力度继续加大，发展电子商务的需求将会更加强劲。电子商务广泛应用于生产、流通、消费等各领域和社会生活的各个层面，促使全社会电子商务的应用意识不断增强。随着电子商务发展的政策法律环境的不断完善，电子商务应用将达到新的广度和深度。

随着电子商务的发展，网上购物也成为了一个时尚。网上书店是一种非常普遍和流行的动态电子商务网站，它使每一个顾客不用出门在家里就能够通过上网轻松购买自己喜爱的书籍。目前,传统书店所具备的功能几乎都可以在互联网上进行电子化模拟。传统书店规模各有不同，但网上交易将有效地改变企业发展空间，对企业竞争力产生不可忽视的影响。

时间在信息时代是显得尤为宝贵，由于种种原因顾客没有时间到书店选购自己想要的书籍，同时传统书店的经营者又无法了解顾客所需要的书籍。这种买卖双方之间信息交流上的障碍成为传统书店发展的瓶颈，而网上书店可以更好地解决这方面的问题，其成本远低于传统实体书店。

B2C（Business-to-Customer,商家对顾客）平台提供的产品在质量、品牌、售后服务等系列核心环节上比C2C（Customer-to-Customer，顾客对顾客）平台有较大竞争优势。B2C电子商务市场呈现逆势“井喷”，并逐渐替代C2C成为网购电子商务的主流趋势。企业、商家可充分利用电子商城提供的网络基础设施、支付平台、安全平台、管理平台等共享资源有效地开展自己的商业活动。

本系统利用网络电子商务新技术,在Internet上实现了基于B2C的电子商务管理系统。开发工具采用，后台数据库采用SQL Server2005。借助web服务器和客户浏览器，客户可以通过网上书店对书籍进行浏览、查询，然后进行购买并生成订单。管理员可以对订单进行处理并向客户发货,本文以软件工程方法学为指导设计并实现网上书店系统,首先对系统的可行性及需求进行分析，接着进行数据库的设计、软件结构的设计，最后对网上书店的前台、后台等进行详细设计并在平台下编程实现。系统运行结果良好，达到预期目标。

INTRODUCTION

INTRODUCTION

With the greater improve of the market economic,promote the economic growth mode and structural adjustment efforts continue to increase,demand for the development of e-commerce will be more robust. E-commerce is widely used in various fields of production,circulation,and consumption and social life at all levels,prompting the society as a whole e-commerce applications growing awareness.With the development of electronic commerce policy and legal environment continues to improve,e-commerce applications will reach a new breadth and depth.
