一种面向对象的工作流管理系统的建模思想

A modeling thought of workflow management system based on object-orientation

工作流建模对工作流管理系统的实现具有重要的作用 .用传统的结构化建模方法得到的模型使得控制流和数据流之间存在紧密耦合 ;面向对象建模方法在抽象方式上又存在缺陷 .对建模方法的缺点进行了分析 。

Workflow model plays an important role in the implement of the WfMS.The model obtained by the traditional structured method results in tight coupling between the control flow and the data flow,while the empirical object oriented method also exists flaws in abstract method.This paper reviews the past modeling solutions,indicates their limitation,and finally brings forward a new modeling thought of object orientation.
