Re: next question determining which columns are in the primary key

I recommend you avoid this, too. If the primary key is composite, store references to it in multiple columns.

If there's agood reason not to do that, then define a surrogate key for the original table, and make your foreign key references to the surrogate key instead of to the composite key.
