Research On Workflow Technology In The Universal Platform Of Web Application System Based On .NET

Web-based application system has dived into all walks of life to modern society. With the increase enterprise information, the development of application system, the quality and efficiency of enterprises will have a very important relationship. Therefore the development of application system in-depth research, enhancement the development of quality, improvement the efficiency of the development of application system has become very important. To this end we have designed and achieved a universal platform of web application system based on .NET for the development of information systems to improve efficiency. In the platform, workflow management system as a very important component gives support to business processes of the information system. First the paper introduces .Net platform and a variety of functions of it provided.Then the workflow analysis of the relevant theory, made on the basis of a simple, visual workflow models. And then provide a model definition.This paper describes the engine from the structure, processes and models available interface definition, many aspects such as the functioning of the flow of workflow system for analysis. On this basis the achievement of the design we can extend the workflow engine. It provides a variety of ways to expand its workflow functionality, simple interface to facilitate the development of personnel available to deploy. Its workflow definition model theory is simple and visual. The business processes can be easily carried out on modeling. At the same time we design and achieve a web-based graphics workflow control system. At present this system has been applied to a traffic information platform.Practice has proved this proposed workflow system practicable, can be used for the actual systems development.
