A system for providing enhanced matching for database queries. The system includes a data source; a data repository comprising a single-sourced reference file; a database comprising a multi-sourced reference file, the multi-sourced reference file having a first unique business identification number corresponding to a business entity; and an intelligence engine processing incoming data from the data source. The intelligence engine determines whether the incoming data matches the multi-sourced reference file and adds the data to the multi-sourced reference file when the data matches the multi-sourced reference file. The intelligence engine also determines whether the incoming data matches a single-sourced reference file contained within the data repository when the data does not match the multi-sourced reference file.
