A reusable data convergency model for integration of heterogeneous data resources
Feng Zhang, Yongshan Wei, Xin Chen · 2009
With the rapid growth of the Internet, numerous data resources, which are distributed, autonomous and heterogeneous, are available for access. Consequently, the integration of heterogeneous data resources is a fundamental issue in the information integration. In this paper, a data convergency model based on XML is brought forward to present the integration process of the heterogeneous data resources. With this model users can construct reusable virtual data resources called VDR. The output structure of VDR is of semantic description, thus the users can choose existing VDRs to construct new VDR for their requirements.
