Re: question about which column(s) are the right foreign key

As a follow up, I now have object versions with the combined primary key
(object id, date and time of object version creation). Now when I need
to refer to an object version in a foreign key, do I let the object id
column itself reference the objects table in addition to it being part
of the foreign key to the object versions table?

Thanks.
