If you have a parent table with two child tables for example, you would normally insert the parent rec, return the identity value, then insert the child rec. However, if the only reason the parent table exists is to make sure the child IDs are unique, you could use a sequence instead and get rid of the overhead of the parent table.

Not sure if this is practical or not, just the first thing that came to mind.
