Research On Service-oriented Workflow System Application

In enterprise informationization domain, it is the key problem how to constant improves business management capability and efficiency for adapting frequently changing of market environment. The enterprise need construct enterprise information systems focusing on business process management. As business process automatization and standardization technology in enterprise, workflow technology is far-ranging applied to not only inside business process management and application integration, but also outside business-to-business integration.Workflow is the computation model of business process, which adopt right model to express business logic and rules, and then implement computing on it. But as the core of workflow technology, workflow management systems provide consistent platform for building and running and inspecting and managing workflow in heterogeneous and autonomy and distributing environment.Nowadays, along with prosperity of web services technology based on internet and service-oriented architecture method, more and more enterprises hope to adopt service-oriented technology to construct business process management platform. By adopting relax coupling system organize method based on opening standard and business-oriented design method of process and service , it enhance business agility and build uniform architecture for business reoccupy and system integration. In this way, enterprise information system is capable of coming true systemic newly business-oriented organizing, and takes full advantage of application function of carry-over application system, and conquer some shortcomings such as worse reusability,difficult to extend system for adapting changing business outside in traditional workflow system adopting Client/Server or Point-To-Point architecture.In this article, we analyse additional workflow technology structure and workflow management system architecture and in-depth research application scene of workflow system of service-oriented, and then bring forward workflow system resolve scheme based on service-oriented architecture and web services technology. In this scheme, introducing service-oriented architecture for designing workflow management system framework, adopting service-oriented method for workflow modeling, analyse feasibility and superiority of building workflow system by adopting service-oriented architecture methodology from different application layer. Then linking implemented workflow management system SO-WFMS prototype, we analyse workflow engine structure and relational key techniques. In SO-WFMS, additional workflow engine is redesigned according to drive requests of different granularity assignment, and it is decompounded three engine, including process engine,service engine and rule engine. Different drive engines execute assignment mapping and exchanging message by interfaces bases on Business Process Execution Language For Web Services standard. It greatly enhances agility and flexibility of workflow engine. In finally, according to choused business process demand of typical enterprise electronic stock , we carry through model,design and implement of enterprise electronic stock workflow system based on SO-WFMS. Considering diversity of business environment, workflow system of services-oriented is multilayer,opening and independentity of technology workflow platform with better adaptability and expansibility by preferably adopting some idea such as BPEL standard,relax coupling rules and business-oriented design method.
