Abstract: 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.

Abstract: Architecture that facilitates discerning integrity of a data handling system. The architecture includes an identification component that periodically applies to data, in a batch mode, a context-based rule, the rule identifying anamolous data that does not satisfy the rule. A healing component is included to further rectify and/or flag the identified anomalous data.
