The Research On Data Flow Manage Frame

Information System as a main part of software System has applied in every business, with the development of society, some of them has not applied very well. It is difficult in keeping system. It has spared developers many time in studying user's demand. We have founded that some problem comes from the vary of dataflow demanding.This paper aim at the problem of the variety of dataflow existed in developing and asserting Information System, and put forward a dataflow manage frame. We see Information System as the aggregate of software module and dataflow between software module, and we do not think about how about the developing of software module, and think about the data flowing between software module, and we design dataflow for customized when dataflow varied. This paper put forward the architecture of dataflow manage frame, and analyzed the every tache of the architecture, and make the data flow model. We descripe the data flow with standard model. When we look into the process of data flowing, we found that the base of data flowing consisted of the mapping of data model, so this paper make a search on data model and mapping model, and put forward the describe language and specification of data model and mapping model, we make a test on this language and specification. As a result, this method is valid.This paper introduced the relative technic. It took the model driven as software developing pattern, and started at the mapping between relation data model, and supported by MOF and MDA, and referenced frame technic, and provided the resolvent of existing in Information System and improved the efficiency of Information System developing and keeping.
