The Design Of Tax Audit System Based On Workflow Technology

With the development of information technology, management information system plays a more and more important role in enterprise's daily work. The enterprise's information system is expected to meet the needs of constantly changing work and to realize the information interchanging and sharing, cooperating with each other, as far as to scientific management and decision-making between each other. Workflow technology developed from the 80's middle period can be met this kind ofdemand .The main object of workflow management is to coordinate everylinks of business procedures to make it run in some definite sequences tofulfill the automation in business procedure by invocating concerned information resource and human resource.In this paper, the concept, basic character, present situation and development of workflow technology and workflow management system are introduced briefly. Both the workflow model and the workflow execution control are researched on a great quantity of reference about the workflow technology and the workflow management system. As for workflow process model, a process model named" direct-graph-with-condition-changing" is proposed . The model can describe "state" which improves the ability to express the model.Message-node is explicitly shown in the model to enhance the description of message transfer. In order to realize the model, we developed a tool for process modeling named WFD, with which end users can model process visually. As for workflow execution control, this paper presents a framework of a relationship-based workflow engine. It consists of three components, namely: organization model, information model and control model. The reasons that the concepts of relationship are adopted to design the workflow engine are thoroughly discussed in the paper. Also, this paper sets forth the principle to design, the representation of and the way to implement the organization, information and control model of the workflow engine, respectively.In the end of this paper, Main work are summarized. The defect of the system is also discussed and the further work is proposed.
