Fusion's matching functionality automates the process of identifying records that represent the same real-world entity (duplicate records) and merging the identified records into a single consolidated record.
For a discussion on data matching, how Fusion implements data matching, and topics you may want to consider when deciding how to configure your matching specifications, see How Data Matching and Consolidation Work.
For instructions on creating, editing, executing, or otherwise managing One Source matching specifications, see One Source Matching Specification Management.
The Stewardship UI is used to view the results of running a matching specification, to manually merge and unmerge records, and to change the selection of consolidated record values. For more information, see Stewardship UI.
