Research And Application Of Workflow System Based On Web Service

Because of the ability of handling difficulty affairs workflow systems are being applied more and more. However, there are still much shortage in workflow system nowadays when Internet technology and e-economic are developing very fast. First, workflow system cannot give support very well to Internet commucation, and flow is lack of dynamic and co-operation characteristic and the integration is usually very bad. So the workflow system is often difficulty to acclimatize itself to distributing application between different organizations and departments. Second, the most workflow system orient the certain domain and end users, it is mingled with the certain enterprise operation regulation and appliance data. The workflow system and the application system is only one. This makes the system high coupling and low flexibility and expansibility and bad usablity. These flaws make the application of workflow system very modest.This paper deals with these flaws of nowadays workflow system and a web service-based workflow system WSFLOW is designed and implemented.WSFLOW designes a minitype kernel which fully contain workflow and web service character and provides absolutely necessarily workflow and web service functionality. WSFLOW is for the professional software developers who use develop tools to architect application system, not the end users. In this way it can be applied every kind of domain. So the problems of tradition workflow system and application system integrate together, bad expansibility and flexibility and maintainability are resolved. As a midmare it's agile and easy to maintain. Development time is obviously shortened when using WSFLOW.WSFLOW put web service to workflow system. Web service is a kind of net resource which can be accessed through URL address. It is relaxed and coupling and flexible. The problems in disaccording communication circumstances,co-operation and integration are solved very well for the standardized characteristic, encapsulation and integration of web service.
