传统系统向面向服务架构(SOA)转变的研究

A Research on Transformation from Traditional System to SOA

传统软件架构无法很好地满足不断变更的多样化需求,而SOA具有可复用、灵活和可扩展等诸多优势。作为实现SOA的主流技术,Web Services的一大好处就是能够集成遗留系统。研究了如何将现有的以数据为中心的传统系统转变为以服务为中心的系统(SOA系统)。首先介绍了SOA的优势及SOA与现有系统的亲缘关系,说明为什么要转变而又为什么能转变。重点针对不同情况说明了该如何具体实施,最后引用了一个保险行业网上投保的例子。

Unlike traditional software architecture, SOA proves reusable, flexible and extendable. Web services, the mainstream technology to implement SOA is able to integrate remainer system. The paper discusses how to transform traditional data--centered system to service--centered system（SO,a,）, including advantages of SOA, the relationship between SOA and object--oriented architecture. A case study is cited for this purpose.
