基于面向服务架构的系统改造与实现探讨

本文阐述了面向服务架构的实质及Web Service技术与面向服务架构的契合性,然后结合一个现有系统的业务,分析其现有架构的弊端,利用面向服务架构设计理念对系统业务进行整合分析,提出一个基于面向服务架构改造方案。方案基于.NET平台和其Web Service技术。文中还就利用现有技术的实现环节及其细节进行描述与分析。最后阐述了面向服务架构的优越性及其一些不足之处,并得出面向服务架构是无关具体技术,以业务为主导的开发理念。

Refactoring and Realization of Existing System Based on Service Oriented Architecture

This paper discussed essence of Service Oriented Architecture (SOA) and its relation with Web Service.As a case study, an alternative solution based on Service Oriented Architecture, is given for an existing system after refactoring the core business to Service Component with the methodology of Service Oriented.The new solution is based on.NET platform and its Web Service technology.The realization process and its details are described in the article,and the advantage and disadvantage about the new solution are given.The paper concludes with that SOA is a business-focus concept and methodology,irrespective with specific technology.
