An Approach and Realization of XML-based Heterogeneous Data Sources Integration

The integration of heterogeneous data sources,which can exploit the information resources effectively and realize the data-sharing,is one of the vexed points in the current data processing field.An approach of hetergeneous data sources integration which is based on the XML middleware is introduces.It firstly introduces the hierarchical pattern of the system framework and the funcitons of each scale,and then specifies several keypoints such as mode exchanging and the technology of XML middleware.Moreover,it illustrates the mapping arithmatic in patterns and the realization of exchanger by some examples.
