| The Subject of my paper is the application research of workflow technique based on SOA. In this paper, firstly I summarized the current state of workflow platform and point out the needs of the power electricity industry. I design and develop a workflow platform and I checked the workflow platform through a business application system. Finally I point out the further direction of the workflow platform.Firstly, I explain the basic concept of workflow platform including process, workflow platform and SOA and so on. I summarize the status quo of current workflow platform and point out the weakness of these workflow platforms and tell of the work of my paper finally.On the basis of summarizing the current state of workflow platform, I explain the architecture, composition of current workflow platform and the technical standard of workflow, the relation of workflow and ESB, ERP. Finally I point out the weakness of current workflow platform and the functional point of the workflow platform in my paper. I explain the entire architecture of my workflow platform. The workflow platform include the workflow engine,the workflow-modeling designer, the API of business application, the management of forms and the monitoring of process.â… explain them particular in this part and finally tell of how to develop the persistence layer. I tell of how I develop the workflow engine. The engine comprise the kernel of workflow engine, task management, service orchestrate, the condition management of transition, process definition and definition policy,participant management, logging management and cache management and event management. I explain them how to develop them particularly.Finally, I validate the workflow platform through a key application system of electrical industry——the promotion management system of state grid. I check it in function, performance and expansibility and so on and tell of the effect of the workflow platform. I point out the weakness of the workflow in this paper and how to improve the platform. |
