Research on the realization method of workflow engine in enterprise information management

This paper aims to discuss in detail a feasible realization method of workflow engine for enterprise information management on the basis of database technology.

Under the guidance of workflow management coalition (WfMC), the data model of the workflow engine is first presented based on the given process model, in which the attributes of process, activity and its relationships with role, application, workflow relation data and transfer condition are marked out. Then the basic control principles of the workflow engine are designed based on the necessary tables of process instances and activity instances, in which the control method of process instance and activity instance are discussed in detail including the creation, startup, management or status evolvement of the instance.

In the research, the workflow engine is successfully programmed as this realization method on the development platform of SQL server 2000 and Visual Studio 2005 and the results show the effectiveness of the workflow engine for inventory information management.

The paper gives a feasible realization method for business process management in enterprises using the advanced workflow technology, which can assign flexibility to the information management and improve the whole performance of an enterprise while facing changing market requirements.
