Lightweight Workflow Management System Based XML

Nowadays, more and more routines of modern enterprises need joining and collaboration among employees. They often involve in different parts and deal with different parts of a complicated task. But most of the existing management information systems fall short of harmonization for multi-colleagues involved in the joint task.WFMS (Workflow Management System) can efficiently solve this problem by using the workflow technology. Nowadays, Workflow technology has being widely applied in the fields of office automation and electronic government, etc. It is the core technology to realize modeling, managing and integrating of enterprises'business process and also the automation of business process. The implement of workflow technology has become an important method to improve the business process and the competitiveness of enterprises.Firstly, the paper analyzes workflow technology and workflow management system. According to the model and structure made by Workflow Management Coalition(WFMC),the paper designs the lightweight WFMS based XML and some advanced technologies such as .NET, XML, B/S is used. Secondly, During the implement of workflow engine, workflow meta-model is introduced and extracted from workflow model. Process definition language based on XML can be used to define workflow. In this way, the activities, rules and participators'relations of enterprise's business process are defined more efficiently. Thirdly, Role-Based Access Control is applied in organization model's design to meet the requirements of complex organization in enterprise. Workflow engine is designed and realized. Database technology is used to store the workflow model and the workflow relative data. Finally, the Workflow technology is applied in the document running system.
