| 摘 要： | BPEL4WS(业务流程执行语言,简称BPEL)是当前服务合成的首选标准语言,但因为它是流程组织的描述语言,所以并不提供处理异构数据的机制。为了解决BPEL系统开发中遇到的数据转换方面的表达和处理问题,提出一种扩展BPEL规范中赋值活动的属性的方法,使BPEL引擎可以满足大部分复杂的数据处理需求,并支持通过业务规则引擎进行数据处理。

| Abstract: | BPEL is currently the first choice of language for services composition,but it has no such a mechanism because it is a language of describing processes. In order to solve the expression and processing of datatransform for developing the BPEL system,this paper proposes an extension to the "assign" activity of BPEL. BPEL engine supporting this extension has been implemented,which can satisfy complex data processing need in services composition. Furthermore,the BPEL engine also supports data processing by business rule engines. |
