Another difference is that database tables are finite and variable,

Oh, relations in database world are certainly not restricted by finite
cardinality.

I thought that computers are finite, so the relations containable in
them are too - even if damn large. There's a big difference between
very large and infinite.

This doesn't really matter. You can still reason about infinite
relations with finite resources available on you computer platform.

Indeed you can. In case anyone is interested in a concrete example:
