电子商务应用：一个基于多层架构的在线商场

论文摘要

当今,Internet的使用遍及人类社会的各个方面,它给人们的生活带来了各种各样的变化,而电子商务就是其中之一。通过Internet处理事务,无数的个人和商业行为更多的获益。电子商务对传统的商业运作产生了巨大的影响。 任何设计能否获得成功的一个关键因素是其系统架构是否合理可行。本文论述一种电子商务应用,它是基于多层架构的网上交易系统。多层架构是一种发展趋势,对企业级运用和基于web的运用产生了深远影响。在线交易系统运行在计算机上,能够通过网络完成在线订货和在线支付。随着在线客户的不断增加,需要系统能够尽量不出错并且随时能够提供服务。因此,本系统在电子商务领域具有很高的可靠性,安全性,灵活性。 在三层结构(即多层结构),中间层位于系统客户端和远端数据库之间。中间层把客户端界面和数据独立出来,这样就提高了整个系统的灵活性,高性能,可伸缩性,可管理性,安全性和可扩展性。在本文阐述的多层架构中,客户端和数据库可以通过中间层进行通信,为客户提供高质量的服务,而这一点也是该架构能为电子商务提供的。 由于Web的大范围应用,Internet标准极大的改变着分布式计算。基于Web的多层架构是基于组件的两层结构的理想发展方向,也比较适合小型网上交易。这种架构正随着网络的发展越来越流行,可以预见在近些年中,这种分布式系统将会得到极大的发展。
