inheritance?

hello,

I would like to collect indexes of a few other tables
into one table in order to access their values more
easier.
like in "urls" table here:

http://www.phpbuilder.com/columns/barry20000731.php3?page=4

But inserting the same values into many tables isn't
very convienent.
Shoul I use inherited tables, aliases, joins?
That metho is the most effective here?
PHP will be used to manipulate the data.

thank you in advance,

ktt
