Research And Implementation Of Workflow System New Model Based On Web Services

Workflow technology is the enterprise business process modeling, business process simulation, business process optimization, business process management and collection, and ultimately the core of business process automation technology. How to make workflow system heterogeneous, distributed and loosely coupled features such as the current workflow system, an urgent need to address the problem. Based on Web Services has a cross-firewall communications, application integration, software reuse, etc., will be introduced to Web Services workflow system, presents a Web Services-based workflow system a new model and the application of the model BPEL language described, Petri net-based activity, accessibility and the nature of the deadlock three structural design of the model has been verified. To solve the system of traditional workflow process reuse, heterogeneous distribution, reliability and so on shortcomings. In the Web Services-based Workflow System Design and Implementation, the paper proposes a three-tier service-oriented architecture to support dynamic and reuse processes, and increase the reliability of business processes, with better flexibility and security.
