1. A computer system for facilitating management of a data mapping validation system, the computer system comprising: a processor coupled to a computer storage medium; the computer storage medium that stores thereon a plurality of computer software components executable by the processor; a signature generation component that receives management information associated with generating at least one data signature of a data source and generating at least one data signature of a data target; a sampling component that receives management information associated with obtaining at least one data sample of the data source and obtaining at least one data sample of the data target; and a processing component that obtains a signature compare output from the signature generation component and a sample compare output from the sampling component, converts the signature compare output and the sample compare output into a common format, and compares the signature compare output and the sample compare output to determine equivalency between the signature compare output and the sample compare output.
