Gints,
There's another aspect to this conversation with regards to the fact
that for warehouse implementations foreign key constraints are often
times *enforced* in the ETL process and not in the database
definition. Insofar as that's the case, the extra expense you
describe in checking that foreign key relationships tie back to a
parent record row isn't incurred.
