Research And Implementation Of Distributed Workflow System Based On Web Service

Extensive application of workflow technology in the enterprise is a revolution ininformation technology field, which is the core of business process, not only toprovide individual activities of the business process support, but also provideautomatic or semi-automatic support for the link between the activities. Therefore,using workflow technology in enterprise information system, human factors canreduce intermediate links business processes, improve the efficiency of coordinationand control between activities, so as to achieve the maximization of enterprisebusiness process.With the continuous development of enterprises, enterprise businessprocesses from the original centralized gradually become distributed, complexbusiness processes need multiple sectors of mutual coordination to complete. Theenterprise of distributed workflow management system scalability and interoperabilityrequirements more and more high.Web services technology is emerging Web technologies on the basis of thedevelopment of technology.It has broad application prospects. because it contains ahuge commercial value, since the birth has been rapid wide range of applications.Web services-based distributed workflow system based on Web services technologydistributed workflow system with technologies such as CORBA, COM-baseddistributed workflow system has obvious advantages, research to accelerate theconstruction of enterprise information significance.Firstly, an overview of the workflow technology concepts and current researchstatus quo, and Web services technology composition with advantages introduced;followed in the development and design of a lightweight workflow engine based on arelational database based on, distributed workflow technology and Web servicestechnology is a combination of a distributed workflow system model based on Webservices, and the composition of the model with the function of each module and theperformance of the model were analyzed; Finally, in order to improve the distributedworkflow system security, the paper proposes a new exception handling, and thecoordination mechanisms of the model, processes dynamically change the processingmethod described in detail.
