The Study And Application Of Workflow Technology Based On WF

With DOT NET Framework continuing upgrade,Microsof in its next-generation operating system,Windows Vista released a bundle DOT NET Framework3.0.DOT NET Framework 3.0 compared with the previous versions,there has been a fundamental framework for change.It includes three new components,we should study the Windows Workflow Foundation(WF)is one of them.It's a completely fill the Microsoft workflow framework vacancies.However,the release time was not long,for how to use this framework,in what manner to the achievement of specific workflow products,as hot discussions by Microsoft and workflow researcher in recent years.To address the above problem,this paper to office automation management of the enterprise agenda as an example,given WF workflow products to achieve the two programmes to meet the needs of different enterprises.In this paper are as follows:1.Reference Workflow Management Coalition(WfMC)standards,the workflow management system function,architecture,the reference model done a theoretical analysis and discussion.2.WF on the workflow operation mechanism,features,architecture and operating environment,and its model of the necessary work to the summary and summary.3.WF is a persistence services and tracking services for the detailed design.4.Based on SharePoint and OutLook achieve WF workflow.In the realization of this programme,as WF SharePoint workflow Runtime,the Trusteeship Council,the WF workflow engine to the secondary packaging,and OutLook as a client,to obtain from SharePoint schedule information.5.Web-based technology WF workflow.In the realization of this programme,as WF ASP.NET to host applications,WF detailed workflow system in the enterprise agenda in the management of the design,function modules,database design.WF and gives some of the work flow services implementation steps.Practice shows that:In this paper,the realization of these two work-based WF product is feasible.SharePoint and OutLook through which to achieve WF work flow,user-friendly and stable operation with the merits,and it was fast,efficient structures work flow products made it possible to improve the efficiency of the enterprises,the cost of saving the enterprise.However,owing to each version of SharePoint provided by the functional interface,templates limitations,it can not be applied to the high performance requirements of the enterprise.By comparison,the second realization of the programme - Web-based technology WF work flow,a better system compatibility,WF fully functional release,the disadvantage was that the development and testing cycle longer.
