基于Web Service的工作流过程模型研究

A Study of Workflow Process Meta-model Based on Web Service

工作流管理和WebService都是新兴的技术,正是将这两项技术结合起来运用于工作流过程建模上。首先分析了现有模型的弊端,接着简要介绍了WebService及其核心技术———Web服务流语言(WS FL),在此基础上提出了一个工作流过程元模型,该模型由流程、活动、活动依赖三部分组成,重点介绍了流程建模的情况,同时也给出了另外两个部分的设计和说明。

In this paper,the two rising techniques of workflow management and Web Service are corporated into modeling of workflow process.Firstly,the disadvantages of existed model of workflow process is analysed, then Web Service and its kernel technique WSFL are introduced in sketch, based on which a workflow metamodel of workflow process is put forward that are composed of flow,activity and the dependence of activity,and the model of process is concentrated on.
