About Oracle Customer Hub (UCM) Survivorship Rules
Survivorship rules are an automated means of doing the following:
Controlling the quality of customer data stored in Oracle Customer Hub (UCM)
Multiple systems connect to Oracle Customer Hub (UCM) with record update and insert requests.
Making sure that Oracle Customer Hub (UCM) presents the most trusted information contributed by each system
Administrators can create and use survivorship rules to govern which updates from which external systems can be trusted at the field level based on the key criteria. Survivorship rules use attribute groups that determine the set of fields to be evaluated by the survivorship rule. The rules use comparison criteria, such as the confidence level of the publishing system or the most recent published data to evaluate whether inputs from given external systems can be used to update Oracle Customer Hub (UCM).
There is an implicit default attribute group which includes the fields that are not explicitly defined in an attribute group definition. Each survivorship rule has a default criterion. If there is no explicit rule definition for a certain attribute group (including the default attribute group), then the default criterion applies to determine whether an external system can update Oracle Customer Hub (UCM).
