Implementation of Metadata Warehouse Used in a Distributed Data Mining Tool

The application of data mining in the area of control systems provides a perfect solution for the obtaining of the control rules fully and accurately. As author, we have discussed some questions on this distributed data mining tool used in control system in some paper. In this paper, some detail technologies and methods to implement the Metadata warehouse used in that distributed data mining tool will be introduced. The main content in the paper will be include composing and Manifestations of the system Metadata warehouse and the information maintenance method of it . Besides, the expression of data source, data mining algorithm, result of data mining (knowledge) and calculation resource in metadata are also discussed. Making full use of the Metadata warehouse, the data mining tool can reduce time of communication in the distributional data mining process greatly and enhance the system's efficiency.
