Hi , in Supercharge your datawarehouse
i have found two contradicting points
one is A Hub Business key can be composite : two of the same operational systems are using the same keys to mean
different things and these keys can collide when integrated back together again.In this case,the record source becomes a part of the
business key.
and the second point is Ä Hub's PRIMARY KEY can not contain a record source.
So, which we can consider, For the uniqueness can we add Record source field in hub's primary key? can you please explain?
