Abstract:

        This paper addresses a Mediator/Wrapper model based multi-source heterogeneous data integration approach, and poses a component-oriented multi-source heterogeneous data integration architecture to share heterogeneous data sources. This architecture divides data sources into many components to facilitate heterogeneous data sources query and hides the distinction of low-layer data sources by the free combination of different components. This enables users to seamlessly and flexibly access heterogeneous data. This effectively solves the sharing problem of heterogeneous data sources.
