Research And Application Of Workflow Engine OSWorkflow In Management System

Workflow is a kind of managing process that can fully or partially be automated. According to a series of process rules, it transfers and perform the document,information,or task between the executants. Workflow engine is the core software component of the Workflow Management System ,and it is also the main component of driving flow work.This paper introduces the four structures of J2EE technology frame,WfMC standard architecture,WfMC reference model and the function of the Workflow Mamagement System. Then it introduces mostly the main content of the research-OSWorkflow workflow engine including the concepts of the basic elements, the purpose of the key package and the class in common use which are analyzed specifically and studied in depth. Moreover,the main xml configuration files and the core principle are discussed,then the database model of some tables relavant with the workflow engine is given.By using workflow engine OSWorkflow,we could pay more attention to the operation and the definition of rules instead of implementing the Petri net or the Finite State Machine without a hard coded mode,which could improve the efficiency of development. The main objective of this paper is to study OSWorkflow engine and how to apply it for the Information. Management System. The main research work : The requirement of the Information Management System is analyzed,including the summarization of operation,the analysis of the operation workflow and using uml use model modeling for the System. In the end,function model comes;Based on analyzing and researching for the J2EE-based Workflow Management System model,the technology of OSWorkflow engine and J2EE architecture are assembled and the technology of the system is given. Moreover the technology of the system database is introduced; Finally, the flows , in the Scheme Management operation of the Information Management System ,using the technology of OSWorkflow engine and J2EE, are defined in the way of OSWorkflow recognization .The System is implemented and described in detail.The application of system manifests that OSWorkflow is a lightweight engine,which is capable of being integrated into J2EE system frame with small cost. Moreover it can control the management of flows and make the software's development pay more attention to business logic. In this way,it can modify the function and the efficiency of the system.
