    摘要: The present leverages data hierarchies to provide a systematic means to determine data differences between equivalent data. This allows disparate data storage systems to efficiently determine divergent data locations by utilizing, for example, data signatures representative of varying degrees of data granularity. Comparative analysis can then be performed between the databases by employing an iterative approach until the desired level of data granularity is obtained. This allows, in one instance of the present invention, discrepant data to be determined without the transfer of large amounts of data and without requiring homogeneous data storage systems. Another instance of the present invention utilizes equivalent logical data views from non-identical data sets to determine data discrepancies. Yet another instance of the present invention determines discrepancies of a federated and/or integrated data system by employing reversible data statistical signatures, providing a simplistic transfer protocol and sheltering each data system from the other's complexities.

    摘要: Architecture that facilitates validation of a data mapping of data from a data source to a data target. There is included a signature generation component that generates a source signature of all or a portion of the data source and a target signature of all or a corresponding portion of the data target, and a sampling component that obtains a sample of the source data a corresponding sample of the target data. The data signatures and data samples are compared respectively and processed with a processing component to determine the status of the validation process.
