一种Web服务模型的动态行为转换方法研究实现

Research and Implementation on Dynamic Behavioral Model Transformation in Web Services

随着业务流程的复杂性与日俱增,编排和协调Web服务的价值也日益被人们所认识。近年来,国内外一些研究机构和IT企业在关于模型驱动架构MDA在Web服务中的应用方面作了不同程度的研究,但仅仅集中于Web服务模型的静态结构转换。根据MDA的思想,在Web服务模型的转换中,使用动态行为的平台无关模型PIM来定义业务流程,并提供将PIM转换成平台相关模型PSM的方法。研究Web服务模型的动态行为转换,讲述用UML活动图定义业务流程,并提供一种如何从UML活动图转换成BPEL的方法。

Web services orchestration and coordination are evaluated highly while business process becomes more and more complex.ln recent years,the application of Model Driven Architecture（MDA） to Web Services has taken considerable attention by some research institutions and IT enterprise from both native and foreign.However,most of that existing research focuses on the transformation of models that express the static structure.According to MDA principle,we will design business process with the dynamic behavioral Platform Independent Model（PIM） during the model transformations of Web services.And we will provide a transformation method for transforming PIM to Platform Specific Model （PSM）.In this paper we present a method of the behavioral models transformation from the UML Activity Diagram To BPEL.
