Based On The Biztalk Of Hws Workflow Application Platform

Since 1990's, the work flow technology, as a new application technology in the field of synergetic work supported by computers , has been widely used to enhance the information degree and work efficiency of the enterprises. However, as the rapid development in the electronic commerce in the internet, the traditional management system of the work flow cannot adapt to that of the request of modern enterprise. Mainly for the system can't adapt to the business handling processes of the enterprise which are getting more and more complex, and lacks flexibility and the interoperability, therefore cannot support the work flow which keeps dynamically changing and trans-organizations.The appearance of the Web Service technology is a leap in the distributing computing field, which would enhance the system's performance largely when applied it to the work flow management system. Web Service is a kind of applied integration model based on the standard, with the natures of dynamic and alternate operation. It can integrate the distributing applications which are used in Intranet, Extranet and Internet.BizTalk is a work flow service frame based on Web Service developed by Microsoft Corporation, it involves a series of work flow management methods based on Web Service, and on its base, the R&D personnel can quickly construct the powerful work flow application management system.Aiming at the disadvantages of the traditional work flow management system, based on deep study of BizTalk HWS, a platform is to be set up for work flow application in this paper. On its systematical frame, a solution is adopted to face SOA based on Web, and on its hierarchical structure N layer truss is used with the natures of excellent trans-platform and systematical toughness; On the work flow model, it is proposed to adopt organization model, resources model, data model and active model which can effectively adapt to the large-scale enterprise service flow. In the flow designing, a work flow constructing method is proposed to use based on the drive of the tasks. And after having been studied the processing mechanism of the active flow tasks, a definition is given about the flow task and the flow duty template, enables the system to model and design the work flow of the enterprise complex businesses quickly, In the work flow dispatch, the flow dynamic scheduling mechanism has been studied based on the flow dispatch engine and the Action task supervisor, including flow dispatch mechanism, design and realization of duty supervisor. And it is discussed about how various functions modules of the system cooperate in detail. At last, an application example is give to illustrate the issues.
