Well, my very personal opinion is that this is less a matter of
database size but more a matter of the demands for availability.
I personally would feel much better to be responsible for a several
hundred GB-database which allows for some comfortable downtime every
now and then than to keep even a small 1GB database up and running
24/7 with no downtimes allowed.
I would not hesitate to use Firebird for the huge 100sGB-DB but I
would really prefer Oracle for the 24/7-thing.
No, I don't want to say that Oracle is more (or less) reliable than
Firebird.
It is more a political reasoning based on
"Nobody ever got fired for buying IBM^h^h^h Oracle"

If you use Firebird and for any reason the database goes offline for
some time, you can bet to hear sooner or later "that would not have
happened with Oracle".
