Software Reuse Techniques And Workflow Technology And Their Application In The MIS

The Management Information System is a system composed by the human, the computer and so on, can collect, transfer, store, process, maintain and use information. Along with swift and violent development in the computer technology, the traditional method of development with difficulty adapted complex and the changeable application demand, although MIS has a lot of method of development. It become the key point which the people pay attention that how to improve the MIS development advancement and introduce the new method of development.Firstly, the current situation and development trend of software reuse and workflow technology are analyzed, the correlative concepts of software reuse and workflow technology are expounded, the key technologies of software reuse are elaborated in detail. Through carries on the comparison to the software reuse, the apphcation system development pattern is proposed based on two-life-cycle model.Then it studied the development method of the application system based on the workflow technology. In view of the MIS domain, it proposes software development frame based on the workflow and software reuse technology, which is organic combination of the J2EE system standard, the component technology and the workflow the technical. The MIS may build on high grade, through the component took the apphcation system the basic composition element. The MIS based on that has strongly controllable and maintainable ability, simultaneously has the strongest response ability on changeable demand, and can accumulate the software wealth continually through components accumulation.At last according to the actually demand, the Contract Management Information System which is three-layers B/S structure based on workflow is designed and realized.
