13. The apparatus of claim 12 further comprising: means for determining whether a possibly matching record can be considered a near-matching record to the input data, in response to failing to find a matching reference database record but finding one or more possibly matching reference database records; and means for applying at least one transformation rule to convert the near-matching reference database record to a plurality of forms, wherein individual ones of the plurality of forms correspond to individual target databases of a plurality of target databases; means for querying at least one of the plurality of target databases for the one or more target database records that correspond to the at least one of the individual ones of the plurality of forms, in response to identifying a near-matching record.
12. An apparatus for database querying, the apparatus comprising: means for receiving an input data query from a requesting source from a plurality of requesting sources, wherein the input data query having input data and an input data type and wherein a first input data query from a first requesting source has a form different from a second input data query from a second requesting source; means for querying a reference database containing validated data, the reference database selected based on the input data type from among a plurality of reference databases, the querying comprising seeking a reference database record that matches the input data; wherein the means for querying further comprises means for seeking a reference database record by applying a set of reference-based mapping rules for matching input data queries from one of the plurality of requesting sources to an associated one of the plurality of reference databases; means for finding a matching reference database record; means for applying at least one transformation rule to convert the matching reference database record to a plurality of forms, wherein individual ones of the plurality of forms correspond to individual target databases of a plurality of target databases; means for querying at least one of the plurality of target databases for one or more target database records that correspond to the at least one of the individual ones of the plurality of forms; and means for retrieving corresponding records comprising target database records that correspond to the at least one of the individual ones of the plurality of forms and transferring the corresponding records to the requesting source.
