摘要 BPEL已经成为事实上的Web服务组合标准语言,利用BPEL控制流图(BPEL flow graph,BFG)对BPEL进行建模,通过模型对服务组合的数据流进行分析,提出一个面向成员服务的数据依赖度量集;通过此度量集可以量化成员服务的数据依赖复杂度,从而分析成员服务对BPEL中数据流的影响程度与范围,为服务组合演化策略的制定及实施提供依据。 BPEL is a de-facto standard language for web service orchestration.Firstly,BPEL is used flow graph to model BPEL,and analyzed the data flow of service composition based on this model.Furthermore,a metric set about the data dependency for member service is proposed.The degree of data dependency for member service can be quantified through this metic set so that can be analyzed the influence degree and scope the member service produces in the data flow of BPEL,and this work can provide the basis for development and enforcement of evolution strategy.
