Research And Implement Of Web Service Generation In Configurable System Based On Workflow

To improve the production efficiency, more and more enterprises introduce information system to manage all aspects of manufacturing.The introducing of information systems accelerate the process of enterprise information and improve production efficiency. After all, for market environment is changing all the time, in order to maintain market competitiveness, business process of enterprise should be adjusted as market environment change, which means information systems are expected to have the abilities to response the process change quickly.The concept of configurable system is so broad. It includes many aspects such as configurable UI, configurable workflow, and configurable runtime.Workflow based configurable system is means to contribute system using workflow technology. User can build business process model of enterprises through workflow editors, information system run according to workflow model.If business process of enterprises changed, the only thing need to do is to edit workflow model through modeling tool, information system can quickly adapted the changing business process.Such is call configurable information system.Workflow modeling is an approach of Web Service composition, which is based on business people's understanding about enterprise business process? The workflow model is interpreted by workflow engine and drive the execution of Web Services.With the advance of enterprise informationization. Many Web Services are exist in enterprises.However, many Web Services can't satisfy the requirement of new business process when business process changed. So it's meaningful to research how to create new Web Service based on existing Web Service quickly.The research works of this paper are as flowing:Introduce concept of inheritance, polymorphism in object-oriented methodology into Web Service of configurable system, make several Web Services generate strategies to further improve the configurable system scalability and flexibility.Analysis the deficiencies of configurable system based on workflow framework, add a new layer called Web Service Factory to the original framework and propose a new framework.Design and implement configurable system based on workflow, introduce the Web Service generate strategies talked above to verify the relevance and effectiveness of the theory.
