Based On The Visualization Of The Bpel4ws Workflow Process Definition Tools Are Designed To

With rapid development of network technology and improvement of enterprise, information resources show their character as distribute, loose calculation, environment of coupling type. Enterprise business operation become decentralized, while Client/Server, Brower/Server architecture and distributed processing technology are growing up. All of these tell us a truth, that the time of centralizd information processing has gone. Now the trend is, large scale,distributed execution environment will make related tasks run more effectively,and we can supervise them closely. Workflow Management technology is considered as the core technology to provide powerful support to business process re-engineering, process management and process automatization. The basic requirement for workflow modeling is that the processes are modeled in a simple and virtual way.Workflow Management Coalition(WfMC) dedicates on the research on workflow management system, and defines the architecture of workflow management system in its literature,as well as design of the function of interface between different parts.Business Process Execution Language for Web Services(BPEL4WS) is advocated by IBM, Microsoft in 2002, it is a brand-new specification. It's related to integration of Web Service, and is becoming more and more popular now.The main works done by the author are listed below:1) Introduce and analyse the notion of workflow and workflow management system,this is helpful for other works;2) Research on Web Service technology and Business Process Execution Language for Web Services, then introduce other languages in current workflow modeling.3) Introduce and analyse the architecture of workflow management system based...
