Writes each record in the master data set with the record that represents the best match in the second data set. The match operation selects the record in the second data set that has the highest match score for the master record. If two or more records return the highest score, the match operation selects the first record in the second data set. Best Match writes each pair of records to a single row.

You can select

Best Match

when you configure the transformation for dual-source analysis.

Writes clusters that contain sets of records that link to each other with match scores that meet the match threshold. Each record must match at least one other record in the cluster with a score that meets the threshold.

You can select

Clusters

when you configure the transformation for single-source analysis and dual-source analysis.

Writes all pairs of records that match each other with a score that meets the match threshold. The transformation writes each pair to a single row and adds the match score for each pair to each row. If a record matches more than one other record, the transformation writes a row for each record pair.

You can select

Matched Pairs

when you configure the transformation for single-source and dual-source analysis.
