Survivor Helper Union Strategy

This strategy combines the data from all source systems to populate the fields in the SBR for which this strategy is specified. For example, if you store aliases for person names in the database, you want to store all possible alias records and not just the “best” alias information. In order to do this, specify the union strategy for the alias object. This means that all alias information from all source systems is stored in the SBR.

The union strategy is applied to entire objects rather than to fields. This strategy combines all child objects from an enterprise objects source systems to populate the SBR. If the source systems contain two or more instances of a child object with the same unique key (such as two home telephone numbers), the union strategy only populates the most current child object in the SBR. For example, if the union strategy is assigned to the address object and each address object is identified by a unique key (such as the address type), the SBR only contains the most current address record of each address type (for example, one home address, one office address, and so on).
