| The present campus network E-commerce system is constructed in a differently and distributed environment. The coordination of the system is insufficient. Inter-enterprise distributed workflow technique is of great importance in the coordinated E-commerce system applications.Workflow technology,as an effective way to control and harmonize implementation of complex activities and information integration,is an advanced method of management automation. Based on the research of current workflow systems,the paper identifies the design idea and following strategy:flexibility workflow. It puts some flexible expansions into the JBPM framework so as to enable the framework to meet the flexibility requirements of campus network E-commerce workflow management systems.With the actual demands of campus network E-commerce information management systems, It studies the architecture and process modeling of workflow framework. The flexible workflow engine design model is identified.The main job of this paper is designing and implementing a flexible workflow management system. It models the workflow management system, including module model,application model,system structure and coordinated pivotal technology. The integration project of the workflow engine using in the campus network E-commerce system is advanced. The degine and implement of the workflow engine are described detailedly,which includes flexible design ides,collectivity degine and implement structure,data model and implement function.The workflow engine can directly reflect the users'current ideas and the real work via the thinking that users participate in the process explanation,which comes from the interactive workflow framework. And also, With scripts, extended attributes and other elements,The workflow engine can express complex business processes,amend process routing and process definitions dynamically.It integrats the workflow engine into the campus network E-commerce system. The testing results of typical application process in the project indicate that,The workflow engine is stable and high-performance; besides,it is fully consistent with the flexibility needs of system and achieves the research aims and project goals. |
