A "Template" database

[Martin Bajc]

Chris, here it is another problem ;-)

I have three databases (DB_1, DB_2 and DB_3).
DB_1 has two entities TABLE_1 AND TABLE_2,
DB_2 has two entities TABLE_1 AND TABLE_3.

So DB_1 and DB_2 have the same table TABLE_1.

Question: colud I make a "template" visio file with database model diagram
(DB_3),
that has TABLE_1 and somehow link to it the other two database's.

The reason why to do it is in the maintaince of the DB_1 and DB_2 database
models
(for example: if I add a new column to the TABLE_1, I'll do it only once in
DB_3 instead
doing it twice in DB_1 and DB_2.) In my case a "template" database will use
like 10 different databases.

Thanx in advance for the answer!
