The Research On Process Service Mocdel And Related Technology

With the development of computer and network technology, the need of process business promote the development of process system, and workflow technology come into being who's concept is the separation of process logic and business logic. During the past ten years, workflow has a rapid development, but now, it is face with a bottleneck, the reason of the bottleneck is the model shortcoming of WFMC, by which, the separate concept can't come true.In the paper, process systems are sorted according to the form of the relationship of the process and the business. The questions of process reconstruction are discussed and a judgement criterion for the process reconstruction is given. Compared with the conception of workflow, process service is defined from the point of system service. New process model is presented according to the need of process service. In the paper, The expression form of 20 classical process logic is presented too, and rule, operation Mechanism etc, these are basic work for structuring a process system based on the new process model. By the comparation of the new process model and three open source workflow system abort expression ability of them, we have the fact that the new process model has a quite ability of expressing process logic.
