You require an understanding of the rules that the MDM Hub enforces to manage timelines of business entities and relationships. At any point in time, the MDM Hub considers only one version of a record to be effective, based on effective start and effective end dates. When you use batch processes, Services Integration Framework, or

Data Director

to change data, the MDM Hub persists the current effective data. Also, when many systems contribute to a base object record, the MDM Hub enforces rules to update the version of the record, based on the contributing effective records.

You can also use user exits to define and enforce custom rules to manage timelines and effective dates.
