Yes, it is, though "big" is relative (as computers grow).  The
key is to hide the details of where things are stored from the
user, so the user doesn't really have to know what is "big"
(today) vs. "small" (tomorrow or today, for that matter).  I
don't think it's so much the efficiency hit of having big
items stored outside the main relation file, as the need for
the user to know what's "big" and what's "small", that's the
problem.

I mean, my background is as a compiler writer for high-level
languages...call me a 1970's idealist if you will, but I
really think such things should be hidden from the user.
