面向企业间集成的Web服务规范化设计方法

Inter-enterprise Integration Oriented Normalized Design Method for Web Services

面向服务的计算被认为是电子商务环境下一种基于 Web 的、用以解决多企业间复杂业务交互的有效手段,但在现实中并没有达到预期的效果。目前对该方面的研究主要集中于技术层面,缺乏有效的方法来支持企业进行服务的识别与设计。本文首先分析了 Web 服务与企业内/企业间业务过程的关系,讨论了适合于 ERP 与电子商务系统集成的服务应满足何种性质,进而提出了服务的规范化模式与相应的规范化方法,重点讨论了如何从 ERP 与电子商务系统的业务模型以及基于构件的软件系统出发,识别规范化服务的途径。该方法对协助企业识别和设计有价值的Web 服务具有重要意义,并为建立企业内 ERP 系统与企业间电子商务系统之间的集成提供了有效支持。

Service-oriented computing （SOC） is thought to be an effective way to tackle complex Web-Based business collaborations between enterprises in E-Buslness environment, but in practice it didn＇t reach the expectation. Current researches focus, mainly, on technological aspects, such as service publication, discovery, binding： and composition, etc. while lack in effective ways to support Service identification and design before they are to be published and discovered by other enterprises. This paper analyzes the relationships between Web services and inter-/intra-enterprise business processes, discusses what kind of properties a ＂good＂ service should have to fit for the integration between ERP and E-Business systems, and accordingly presents a Service Normal Form （SNF） and the corresponding service normalization method. In this method, the way of how to identify normalized services from business process models, and how to create close mapping between services and legacy component-based information systems, are emphatically discussed. This method provides great significance to help enterprises identifying and designing valuable business services.
