FOREIGN KEY Constraints in a Data Warehouse  




ENABLE NOVALIDATE can quickly create an enforced constraint, even when the constraint is believed to be true. Suppose that the ETL process verifies that a FOREIGN KEY constraint is true. Rather than have the database re-verify this FOREIGN KEY constraint, which would require time and database resources, the data warehouse administrator could instead create a FOREIGN KEY constraint using ENABLE NOVALIDATE."

You could ENABLE .... NOVALIDATE if you are 100% sure that the data was validared during ETL.

This is somewhere in the Datawarehousing Guide in the documentation.
