The one or more pair-wise combinations each include a first field and a second field from the database. The method then determines a distinct count for each entry in the first field grouped by the second field of the one or more pair-wise combinations, and determines that the distinct counts for each entry has a value equal to one. The method further includes based on the determination that the distinct counts for each entry have a value equal to one, setting the first field in the pair-wise combination as the parent and the second field in the pair-wise combination as the child in a default hierarchy for the data set.
