Research On Data Integration Of CIMS In Steel Rolling Enterprise

One of the cores in CIMS is data integration, whose target is to share the data from different subsystems, to utilize the resource effectively and finally to improve system's peformance. There is much data in the different format in rolling enterprise from the different sources or for the different use.Many kinds of data processing technology are needed to support them.Through studying the enterprise information and the actuality of Tangshan Steel Group, this paper analyse and study the data integration in the middle-small rolling enterprise. The main contents are following as:At first, This paper introduce some concepts and applied actuality and prospect of CIMS, therefrom this paper educes the system constructure of the rolling enterprise.Then, this paper analyse the data heterogeneity and introduce some technologies of data integration.In succession, this paper study the problem of data integration of the three subsystems in CIMS.At last, this paper introduces the use of data integration in the development of CIMS/MIS in Tangshan Steel Group.
