Study Of Complex Information System Reconstructing With Workflow And Component

Intensifying struggles unexpectedly in which along with the market disappears with the customer takes the trouble the transformation, enterprise's production management pattern and the process can carry on the change and the improvement unceasingly, serves also will certainly to change in its management management information system function and the structure along with it.Traditional constructing method that face to achieve some functions of informationization system is more and more not to be able to adapt the modern enterprise to implement the fast service flow to be bom again (BPR)'s need. Therefore founds the recent information system to construct the method to adapt complex information system restructuring is the question which the current software engineering must be faced.In the article ,we realized the separation between business logic and business handling by taking the technology of workflow and component into the process of structuring information system; Encapsulated the business processing by component;defined the business logic by process definition of workflow; the workflow-engine to come the service flow which the instantiation, the management and the monitoring define, thus will enable the information system to obtain in the future possible reconstruction cost reduces.
