Research and application on metadata integration for data warehouses

Metadata integration is an important issue in metadata management. It presents a metadata integration strategy based on SOA architecture for data warehouses. In this strategy, Web Service is adopted as application frame; Metadata is modeled by CWM and metadata encapsulation is designed in XML. The metadata from distributed data warehouses has been efficiently integrated and reused. It focuses on the architecture of the system, the structure design of CWM, as well as various Web Service methods creation and call. Finally, verify the feasibility, effectiveness and practicability of this solution by experiment.
