Collection and Realization of XML-based Heterogeneous Data Sources Integration

The integration of heterogeneous data sources,which use the information resources effectively to realize data-sharing,is one of the vexing issues in the current data processing field.An approach of heterogeneous data source integration based on the XML middleware is proposed.This approach firstly introduces the hierarchical pattern of the system framework and the functions of each scale,and then specifies several key points such as mode exchanging and the technology of XML middleware.Moreover,it illustrates the mapping arithmetic in patterns and the realization of exchanger with specific examples.
