Abstract


sector data resources more difficult, and restricted the unit of analysis and decision making . Therefore , how to quickly integrate this information and provide a unified query access interface to become all units need to solve the problem . This article discusses the need to address the integration of heterogeneous data and existing heterogeneous data integration strategy, Heterogeneous Data Integration System Based on SDO framework designed on this basis . Framework Mediator architecture is based on the introduction of the SDO data access model to reduce the complexity of heterogeneous data source access , use unified format XML document shield the local characteristics of the underlying data source , and integrated transparency , flexibility and scalability . Explained the hierarchical structure of the system as a whole and the detailed design of the modules of the the integrated middleware layer and integrated access layer structure . A key component of the system module , and gives a concrete realization of the class interface . Finally, the system testing process, testing to achieve the desired effect , indicating the feasibility and correctness of the system . The design and implementation of the system was summarized and put forward for further improvement and research .
