Abstract: A computer-implemented method includes accessing a plurality of data records, each data record having a plurality of data fields. The method further includes analyzing values for one or more of the data fields for at least some of the plurality of data records and generating a profile of the plurality of data records based on the analyzing. The method further includes formulating at least one subsetting rule based on the profile; and selecting a subset of data records from the plurality of data records based on the at least one subsetting rule.
