Self Matches. Use a self match to link a data source to itself. Give new matches short, descriptive names consisting on only letters and numbers. The Specify Match dialog is used to create and test a linkage model. The Perform Match dialog is used to apply the linkage model to your standardized data. The Review Match dialog is used to examine linked record pairs and analyze linkage results. When you select a row for an existing match, Access table links and queries for the selected match are recreated to reflect prior work. This can take several minutes, depending on the amount of work already done. Once you have selected a row, you can switch between Specify Match, Perform Match, and Review Match without further delay.
