Modeling and Application of Data Correlations among Heterogeneous Data Sources

摘要：

Data correlations are relationships among heterogeneous data. They reflect the correlations among the heterogeneous data sources on business logics, and are very significant to data exchange, data integration and so on. Traditional methods of data exchange neglect the direct correlations among data, and meanwhile. existing data models have limitations on expressiveness. In order to solve these problems, referring to the ideas of the hyperlinks and data correlations of web services, the concept of data correlations among heterogeneous data is proposed, which expresses data correlations as static expjicit declarations. The abstract model of data correlations and its XML implementation is given, and the application of this model is discussed in detail, Finally the performance is analyzed and compared through experiments.
