Harmonization is the process of deduplication - taking multiple records that are deemed to be for the same underlying real-world subject and producing a single resulting record.

For example, a customer is represented in multiple systems but each system has a different amount of detail or even conflicting information on record. Similarly, a single system may have multiple instances for the same underlying real-world person.

The Harmonize duplicates step takes groups of records that are considered to be duplicates (we call them clusters) and allows you to create a single resulting record for each cluster by applying sophisticated business rules.
