1. A method for separating previously matched records, the method comprising the steps of: determining whether a particular identifier in at least one record representing at least one entity is: (1) common across records representing at least two different entities and (2) no longer generally distinctive of a record representing a single entity; separating records that were previously matched based on the particular identifier, when the particular identifier is determined to be: (1) common across records representing at least two different entities and (2) no longer generally distinctive of a record representing a single entity; storing the separated records; adding the particular identifier to a list of common identifiers, when the particular identifier is determined to be: (1) common across records representing at least two different entities and (2) no longer generally distinctive of a record representing a single entity; and prohibiting any additional matches of records based on the particular identifier when the particular identifier is determined to be (1) common across records representing at least two different entities and (2) no longer generally distinctive of a record representing a single entity.
