Business processes play important roles in enterprise's management, for there are various business processes in modern production and management activities. Among the functions WFMC should implements, modeling the business processes, supporting automation and continues rules are most essential.Workflow technology can streamline the business process, and improve the competitiveness of the enterprises.The workflow management system is a software system which focuses the workflow definition and manages the execution of the workflow instance; its runtime architecture can be centralized or distributed. This paper focuses on the systematic structure and execution technology of the workflow management system, and proposes a distributed J2EE-based structure. Compared with other traditional schema, this structure meets more needs of organization.The thesis first gives introductions and comparisons with workflow technology and WFMS,and draws analysis of the most popular distributed computing platform J2EE,gives introductions to the design the framework of DWFMS based on J2EE,gives introductions to the design schemes of customer application ties,engine service tier and data service tier in detailers.The workflow management system designed and realized in this paper has such advantages as facil and visual flow design, easy operation, convenient maintenance. When new business workflow appears during enterprise's information construction, workflow technology is needed. We can easily work out the workflow with process-design tools. During the operating process, workers can carry out management effortlessly on the monitor interface, thus satisfy various needs of enterprises.
