基于UML的业务流程建模及到BPEIAWS的转换

IBM、Microsoft和BEA于2002年联合提出业务流程执行语言（Business Process Execution Language for Web Services，BPEIAWS或BPEL，后更新为WSBPEL）是用于在不改变Web Service正常运行的情况下，将多个Web Service集成起来创造出新的业务模型和业务流程。但是开发BPEL应用是一项繁琐而枯燥的任务，业务流程建模和BPEL开发之间并没有建立直接的关系。在对UML和BPEL深入学习的基础上，提出通过构造型和键值方法扩展活动图，并采用扩展模型对业务流程建模，最后定义了UML模型到BPEL的映射。利用图形化方式开发BPEL业务流程具有开发速度快和易维护等优点。

The Use of UML for Business Process Modeling and Conversion to BPEL

IBM, Microsoft and BEA were worked together to put forward Business Process Execution Language for Web Services （BPEL4WS or BPEL）in 2002 ,which were used to integrating web services and then creating new business model and Business Process, if only those Web Services running in the regular situation. However, the work of exploiting the applying of BPE/-AWS is so complex and dull. Based on the thoroughly studying of UML and BPEL4WS ,putting forth using Constructive and key-value to extend Activity Diagram and use it for business process modeling, and then defining the mapping from UML model to BPEL. Using a graphical method to develop BPEIAWS business process have the advantage of fast speed and easy maintenance.
