Research And Realization Of A E-government-oriented Lightweight Workflow Management System

The E-government affair is a management pattern of government affair based on computer network technology, focused on share, communion and collaboration as well as structured with government affair information flow and relative integrated work flow. It will makes government work more efficient, service more better and expenditure more less by the configuration and the recombination of workflow.Workflow Management System(WfMS) can effectively support the automation of business process. As a technology which manages and integrates the routine matters, WfMS can advance and optimize the business process, improve the work efficiency, achieve better control of the business process, and improve the service quality and the flexibility of the business process, etc. The Management Information System(MIS)-based on workflow technology has great flexibility and adaptivity, and can make the government work more effectively. So it has greatly applied in the E-government affair field recently, and the research of workflow application has become one of the hotspots in software developing field.This paper first gives the research background and significance. Then introduces the problems and the current research situation in and abroad, raises the topic and research content. Secondly, introduces the origin and development of workflow and the basic concept about workflow and WfMS, gives the system structure of WfMS. Thirdly, to analysis the reference model proposed by Workflow Management Coalition(WfMC), Author designs a structure model of WfMS based on .NET. To strong the descriptions in status and conditions, author studys the reference Workflow Process Model provided by WfMC and presents a Expansion-Oriented Workflow Process Model on the basis of activity-network-diagram, the condition-restricting was added and the"status"and"conditions"was introduced into model, it also greatly improves the flexibility and adaptability of the system. The paper gives a method about designing a lightweight workflow engine based on relational database, introduces the implementation and design of component interfaces and engine database in detail. This engine can deal with business process flexibly, and meets the needs well in E-government management information with stability and scalability. At last, uses the workflow technology in the NPC Bill Management System, it can be integrated with the existing application system conveniently and meets the needs well in actual business.The paper makes an intensive study of the workflow management technology, not only realizes a lightweight workflow engine but also studys the features of the MIS in E-government, and uses the workflow technology in the information management in E-government. It has certain research significance with improving the government efficiency greatly. At last, combines the actual business in the NPC Bill Management System, realizes a complete flow of a workflow process.
