企业信息管理中的工作流引擎实现方法研究

In this paper, a feasible realization method of workflow engine is discussed in detailed for enterprise information management on the basis of database technology. Under the guidance of workflow management Coalition (WfMC), the data model of workflow engine is presented firstly based on the process model given, in which the attributes of process, activity and its relationships with role, application, workflow relation data and transfer condition are marked out. And then the basic control principles of 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 our research work, this workflow engine is programmed as this realization method successfully on the development platform of SQL server 2000 and Visual Studio 2005 and the results shows the effectiveness of the workflow engine for inventory information management. Our achievements give a feasible realization method for business process management in enterprise using the advanced workflow technology, which can assign the good flexibility to the information management and improve the whole performance of enterprise while facing the changing market requirements.
