Record matching system

The present invention discloses methods and systems for an improved Enterprise Matching Service ("EMS") that is designed to match incoming data records to a database of records, using less system resources and using those resources more efficiently. The EMS identifies potential matches by generating unique identifiers and match codes for incoming data records, and then matching the unique identifiers and match codes to pre-generated unique identifiers and match codes for database records. Various match sensitivities are embedded in the pre-generated match codes, so an extensive match is handled by a simplistic "one to one" match between match codes in order to identify a subset of potential matches. Once a subset of potential matches are identified, the methods and systems weigh the subset of potential matches to determine whether there is a match. ME 203420767_1
