The Design Of The Distributed Workflow Engine And Radio Approval Management Applications

With the widely application and rapid development of radio technique, the work of radio management is getting heavy and complex. The implementation of administration admission law requires radio examine and approve management to be standard and actual effect. So, building a science, standard, flexible management mechanism to enhance the level of radio management becames a urgent work needed to be done.After analyzing the process of radio examine and approve, I introduced workflow techniques to radio management to make the processes of radio examine and approve management to be more scientific, more standard, and more automatic. At first, I researched some relevant criterions of WFMC, then, 1 found out the research and product actuality of workflow technique at home and abroad, and analyzed kinds of workflow models and fundamental techniques. At last, I proposed the framework of distributed workflow engine and it's realizations mechanism, according to the needs of reality.In this paper, first, I analyzed the actuality of radio management broadly and deeply, and then introduced workflow techniques to radio examine and approve process. A distributed workflow platform driven by document is carried out to realize radio examine and approve process automatically and intelligently. We discussed the workflow model based on document driven in details; the design of document, and the realization of platform are also given.XML (Extensible Markup Language) was used to design the document in examine and approve process, and J2EE (Java 2 Platform, Enterprise Edition) structure, EJB technique and database technique were adopted to design and realize the distributed workflow platform in layers. Moreover, uniform interfaces are also designed to realize the secondary development conveniently. It solved the problem of transmitting data between two different systems that Java was used to program and XML was used to be...
