The Design And Implementation Of Workflow Engine Base On SOA

In recent years,computer supported cooperative work technology has been widely used in various enterprises and institutions.With the increasing complexity of the business scene and the improvement of the management ability in the company.We can often see that the update speed of some enterprise's workflow management system is far behind the speed of the enterprise management ability.The maintenance of these workflow management system is difficult,high maintenance costs,and can not be flexible with the need to change.According to this situation,the author enhanced the original workflow engine based on the SOA concept.To achieve the function of task template quick reuse,task template quick change,task instance version management.Not only help enterprises to reduce the cost and save the time for maintenance of the workflow management system,but also further help enterprises to improve the working process of the analysis and management capabilities.The research work of this paper mainly has the following aspects.Firstly,confirmed the theoretical foundation for this article base on the research of background,the theory of SOW and workflow.Secondly,proposed the solving target base on the demand analysis.Then,proposed the enhancement requirement of original workflow engine process definition module,interface module,the workflow engine module and static structure based on SOA theory.Subsequently,describe the enhancement content of the object dynamic behavior,and focous on the key business scene of the task template quick reuse,task template quick change,task instantiated and task version management.Finally,through the function testing,we not only check the bug of the system,but also compare the efficiency of the workflow engine.It further confirms the advanced nature of the enhancement design.The main points of this paper lie in the following aspects.How to improve the efficiency of workflow template creation and maintenance,How to support the workflow change task template in the execution process,These improvements will allow the workflow management system to increase the response rate to the demand.How to keep the information in the task execution process,Obtaining this ability will allow managers to improve the management of the work process.The paper show the problem solving process by structure according to the idea of UML and OO.
