Research And Implement Of Graphical Workflow Modeling Technology

In the enviroment of market economy,market is changeful.How can make enterprises press close to the market to maintain the life-force and competition of the enterprises?it is the question of enterprisers and the cause of IT man. In order to survive and develope in the enviroment of market economy,enterprises must maintain the quick reaction to the market.Workflow technology is one of the quick developed new technologies of computer applications.As the implementation of workflow technology, Workflow Management System has been serving for many enterprises.In some sense,the implementation of Workflow Management System is to enhance the quick reaction to the market of enterprises and reduce the management cost, and enhancing the life-force and competition at last.The implementation of Workflow Management System is separated into three phases: Modeling,Instantiation of model and exectution of model.Among the three phases, it mainly model the processes of workflow in the phase of modeling,expressing the business process in a way that computer can understand. An excellent workflow model is the key and foundation of implementing a Workflow Management System which possesses excellent flexibility,reliability and usability. Workflow Modeling influences the performance of Workflow Management System directly,such as correctness and efficiency. So it is very neseccary to design and carry out an excellent Workflow Modeling System.The paper mainly research graphic Workflow Modeling System, and have have success with Workflow Modeling Technology.At first, the paper introduces the background of the research and the structure of this paper, and introduces some concepts about Workflow,and analyzes the framework of Workflow Management System,criterion and standard what the Workflow Management Coalition (WfMC) has found, and mainly introduce the inerfaces of the Workflow Reference Model that have something to do with the paper.Secondly,the paper analyzes the technology of data transmission which is base on SOAP,preparing for the design of data transmission.At last, on the basis of the research of XPDL, the paper analyzes and designs renewedly a Workflow Modeling System, and optimizes the sutructure of the system, and change the store method and transmission method of workflow model data,and carries out the mapping from Workflow Process Model to XPDL.In order to reappearance the graphical workflow model,the paper designs a method of storing data to store the datum of graphical workflow model.
