When we started to provide flat rate charges for all long distance in
each province (averages 1.8 cents a minute) our processing requirements
and infrastructure load jumped dramatically. We had to scramble to
upgrade systems, replace switches, upgrade customer service needs, we
had our hands full..... except when it came to our database systems. We
added a few more external raid arrays and added some extra files to our
file list. Painless.

Firebird is more than capable of being a data warehouse production
server. It is even used as a embedded control database in our SS7
network switches which are rated for five9's reliability.

I do not think we are the only company using Firebird for such
environments, as such, you would probly be extreamly supprised by the
number of people who use it daily without knowing.
