摘　　要：软件解决方案所面临的问题是在部署体系结构时不断增加的多态性、复杂性和分布性,这只能使问题复杂化。随着互联网络技术的出现,系统设计者必须重新评估多层体系结构的适用性,并且评定对每一层来说哪些技术是适用的。这篇文章重新评估多层体系结构中的设计问题,讨论在应用程序间的消息传递中,认为传送代码还是传送数据是比较好的方法。基于J2EE和.NET架构技术,文章最后推荐一个多层体系结构中一个以数据为中心的设计;根据已有的经验,建议软件开发中同样提出一个改良的交互式软件过程的螺旋模型。The increasing heterogeneity, complexity and distributed nature of deployment architectures only serve to compound the problems faced by software solutions. With the advent of the Intemet and web technologies, system designers have had to reevaluate the applicability of multi-tier architectures, and assess which technologies are appropriate at each tier. The design issues of multi-tier architecture is evaluated and debate whether it is good to move code or data to communicate messages between applications is debated. Based on the latest technology of J2EE and. NET framework, recommend a data centric design of multi-tier architecture. Based on experience a modified interactive software process spray model is suggested.
