Uniform Representation Model for Metadata of Data Warehouse

  • Department of Computer Science and Engineering, Beijing Institute of Technology, Beijing100081, China

  • Received Date:2001-05-23
    Abstract
  • A uniform metadata representation is introduced for heterogeneous databases, multi media information and other information sources. Some features about metadata are analyzed. The limitation of existing metadata model is compared with the new one. The metadata model is described in XML which is fit for metadata denotation and exchange. The well structured data, semi structured data and those exterior file data without structure are described in the metadata model. The model provides feasibility and extensibility for constructing uniform metadata model of data warehouse.
