在面向业务的体系结构中实现业务合成

Service Composition in Service-Oriented Architecture

基于Web业务平台中立和自制的特性,通过结合使用由不同业务提供方提供的基本或复杂业务,业务提供者和应用开发商能够向用户提供新的增值业务,构建高级的商业事务.为了解决合成业务的构建问题,对合成业务分类、业务间关系、流模型和合作关系约定等问题进行了研究.以图的方式描述了合成业务,提出了相应的构建准则与方法.另外,提出了一个构建合成业务的整体框架,用于对合成业务的整体生命周期进行管理.

The platform-neutral and self-contained natures of Web services enable service providers and application developers to engage other Web services in order to develop new value-added services and complete higher-order business transactions by using existing elementary or complex services, possibly offered by different service providers. In order to complete service composition, in this paper, composition service is described in a chart diagram form, a series of approaches and guidelines are presented based on analyzing composition service types, relationships between services, flow model and collaboration relationship agreements. In addition, an integrated construction framework is presented to manage the entire life-cycle of composition service.
