Comparison Methods Used by the Survivorship Rules

The survivorship rules use the following comparison methods to evaluate the quality of the object fields associated with an attribute group:

• Recent. Compares the date for the field data of the object attribute group against the date of the updating message. The most recent data survives.

• History. Compares the date for the field data of the object attribute group against the date of the updating message. The oldest data survives.

• Source. Compares the confidence level of the external system that contributed data to attribute group fields in the object against the confidence level of the external system of the updating message. The data with the highest confidence level survives.

• External. Indicates the attribute group settings that enable you to configure any supported rules engine to set specific survivorship rules.

• Golden. The Golden Wins rule stipulates that the values stored in Oracle Customer Hub (UCM) will always win over the incoming record, or in the case of merge, the surviving record's value will always win over the victim's.

• Contributor. The Contributor Wins rule stipulates that the values sent by external application into Oracle Customer Hub (UCM) will always win over the values in the existing best version record, or in the case of merge, the victim record's values will be retained over the surviving record's.
