Abstract


SOA(Service-Oriented Architecture), with the same as process-oriented,object-oriented and component-oriented, is a software approach of formation and development。SOA can be understood as the "abstract, loosely coupled and coarse-grained" software architecture. According to service requests,It can deployment, composition and use loosely coupled application groupware by distributed network, and provides a new way to set up a collaborative system.Workflow is the prevalence technologies about management and integration of routine affairs, by adoption of management of business processes, workflow can improve and optimize business processes, improve operational efficiency; achieve better control of business processes, improve service quality; and improve flexibility of business processes.This thesis starts from the SOA architecture and workflow technology theoretical knowledge, expounds the relationship between them. On the background of the research and development on manuscript circulation and management system of Henan daily ,it researches on the software development architecture, principles and methods based on Workflow and service-oriented .The paper first proposes the idea to adapt the level of division in the service-oriented software development architecture, and gives the corresponding design pattern; and combines with workflow technology , it will apply SOA architecture to Synergy System. The paper will give the research on the key technologies such as collaboration model, collaborative control mechanisms, system structure of the service-oriented collaboration system.And on this basis, combined with the classic object-oriented analysis and design method (OOAD) and the traditional software architecture layered thought, the thesis builds on the foundation of SOA-based application development model architecture, The model is divided into five levels: express layer, business facade layer, business logic layer, data access layer and data layer.Finally, combined with the examples Henan daily manuscript circulation and management systems, based on the prototype of Work flow model, and on the basic framework of Service-Oriented architecture, the thesis builds collaborative workflow service framework in distributed environment. By using .NET development platform, the thesis completes the implementation of workflow-based and service-oriented distrib-uted collaborative system.
