Research And Design Of Service Composition Workflow Engine Based On SOA

Workflow technology provides strong support for inter-enterprise cooperation and Web service applications,and is the core technology for automating business processes.However,with the rapid development of contemporary enterprises,the management of business processes within the company is more cross-platform and heterogeneous.Traditional workflow technology has been difficult to meet this demand.After analyzing the problems existing in current workflow management system,this paper proposes a workflow engine construction model of Web service composition based on SOA architecture,which combines Web Service technology,service composition technology,and service orchestration technology BPEL.The main work of this paper is as follows:(1)Introduced the related concepts of workflow technology,and expounded the function characteristics of workflow management system,analyzed the functions and interfaces of workflow reference model in detail,and conducted an inductive analysis of the current mainstream workflow engine.Discussed the framework of SOA,summarized the basic construction principles of SOA,and studied the related implementation technologies of SOA.(2)Analysis of the advantages of combining workflow technology with SOA architecture.Based on the SCA service component architecture and BPEL engine,the overall architecture of SOA-based service composition workflow engine is given.The execution mechanism of the workflow engine is analyzed in detail,and the relationship between the components inside the engine is discussed.Combining the characteristics of the service component and the transport protocol in the SCA architecture greatly improves the flexibility and loose coupling of the workflow engine,and solves the problem that the traditional workflow engine lacks support for heterogeneous environments.(3)Based on the design of the overall architecture of the engine,the detailed design and implementation of each component module,combined with a logistics delivery system,completed the practical application of the workflow engine,and verified its effectiveness and practicability.Achieved the expected research goals.
