Research & Implement On Enterprise Workflow System Based On Windows Workflow Foundation

As a result of changing rapidly in modern society, In the course of the Enterprise Information System's implementation and development, the update speed of the enterprise management information system is very difficult to synchronize with the business process, and difficult to maintain, it has become a difficult problem in the process of the implementation of enterprise information management system.For this reason, this paper advanced WF-based workflow technology and designed solutions of WF-workflow application platform framework for small and medium enterprises. The main characteristic is that the enterprise workflow and the application program can separate from each other, and this makes the dynamic modification process in the process of running the information systems, having a good maintainability and adaptability.First of all, the author made an In-depth study on the workflow run-time environment, persistence services, as well as follow-up services of the WF-workflow technology. Based on the research of the WF-workflow description, designed the operation of rights management and task management function. In the process of the implementation, the author studied the use of LINQ (Language Integrated Query) technology to make XOML description language describe data from relational database mapping. In the designing process, took the use of the idea of the N layer of software architecture, the system is divided into the data layer, business layer, application layer. Made the system structure clear, having good scalability and maintainability. Application software development and deployment should take use of the distributed architecture.Contrapose the workflow of Hubei Artificial Limb Orthopedic Technology Center's client service, handle the WF-workflow technology to carry out the enterprise information system of information management solutions. Application of the combining of the state machine workflow and the order of the workflow method carried out the overall business processes of enterprise information system. And applications with the mechanism of the dynamic modification of workflow to achieve the workflow dynamic configuration of approval of applications for business processes. Currently, the Hubei Artificial Limb Orthopedic Technology Center's Customer Records Management System and Toll Collection System has been in use in the enterprise and obtained good results and have been promoted to other businesses in the industry.
