Talend Data Stewardship

A Merging campaign enables you to merge several potential duplicate data records into one single master record. Source records can come from the same source (data deduplication) or different sources (data reconciliation).

Campaign owners can create the campaign to determine the structure of the data to be managed, the actions to be taken on data and which data stewards to work on what tasks.

One common use case of data deduplication is same customers appear as separate records in your CRM system. You would like here to match records in order to identify duplicates. A MERGING campaign enables you to decide what fields to use to determine a match and merge the records. Once data is deduplicated, a Talend Job can be used to reupload the cleansed data to CRM.

For a real world use case about data reconciliation, see Adding a Merging campaign to reconciliate contacts.
