Trust and Validation Rules

Trust and Validation Rules

After the
MDM Hub
 flags the deleted records from a source system, trust and validation rules govern the behavior of the delete flags and end dates. The trust and validation rules help determine the most reliable data.
When the
MDM Hub
 detects that the column values in a base object record are hard-deleted in the source, it uses trust and validation rules. The trust and validation rules determine when these base object columns must be overwritten by values from another source system. The
MDM Hub
 uses a validation rule to downgrade the trust percentage on all the trusted columns for a deleted source record. The values in the base object record that were contributed by the deleted source record remains in the base object record. The
MDM Hub
 replaces the deleted values after another source system provides an update with a higher trust to overwrite the values from the deleted source record.
