摘要
介绍了工作流的基本概念及架构,并在此基础上引入了工作流基于XML的过程定义语言XPDL 及应用XPDL进行工作流建模的要素,最后给出了工作流的关系存储模型及其基于组件的实现机制.
This paper introduces the conception and architecture of workflow. It also introduces the workflow process definition language XPDL and the elements of applying XPDL to build the workflow model. In the end, we give the relational data base conceptional model and the mechanism based on component.
