Sure, but *infinite*? Or were you exercising hyperbole?
With One Big Database, you can get a SAN and attach a whole lot of
disk space, but your mobo will only accept a certain number of DIMMs
and processors of certain designs. And when your growing mega
database maxes out your h/w, you're stuck.

For example, it is "common sense" to white-power racists that
whites are superior to blacks, and that those with brown skins
are mud people.
However, that "common sense" is obviously wrong.
