【摘要】 Web服务的商业流程执行语言(简称BPEL或BPEL4WS)是由IBM／BEA/Microsoft等几家厂商联合提出的一种基于XML的工作流定义语言,可以作为企业工作流建模的基础。但是目前能够图形化自动生成符合BPEL4WS规范的流程设计器并不多,基于这种现状,本文在现有的工作流的研究基础上,提出一种符合BPEL4WS规范的工作流平台。本文首先介绍了工作流和BPEL的基本概念,然后给出了该流程设计器的可视化设计,最终给出一个已在攀钢成功应用的工作流设计器。更多还原

【Abstract】 BPEL4WS (Business Process Execution Language for Web Services) is a type of workflow defining language submitted by IBM/BEA/Microsoft and so on, which is based XML and can be used as the base of workflow modeling. But there were few of workflow-modeling tools that can generate BPEL4WS automatically. Based on the research of workflow, a workflow platform conforming BPEL4WS specification is designed and implemented in this paper. At first, the basic concepts of workflow and BPEL4WS are introduced. Then the visual design of the workflow-modeling tool is described. Finally, the paper provided a workflow builder, which had been successfully applied in Panzhihua Steel Cooperation.更多还原
