You can use the tMatchGroup component to detect duplicates and define how to merge similar records to create a master record.

Creating a master record is an iterative process: each new master record can be used to find new duplicates.

You can choose between two different algorithms to create master records:

  • Simple VSR Matcher

  • T-Swoosh

The main difference between the two algorithms is that T-Swoosh creates, for each master record, a new record that does not exist in the list of input records.
