Abstract
A software system and method is disclosed for creating and maintaining an audience member database based on multiple source audience member databases. Rankings of relative accuracy of data elements of each source database are maintained. To determine whether a given source database record represents the same audience member represented by a record of the target database, comparisons are made of various non-encoded and encoded fields of the respective databases to identify the most closely-matching target database record. If such a record is identified, only those fields from the source records that have a higher accuracy ranking than the fields in the target database are updated. The target database itself may be directly editable and its fields may be associated with accuracy rankings. Optionally, the user may select parameters to specify how closely candidate match records must match in order to achieve the optimal balance of speed vs. accuracy.
