Hello

I read somewhere that a good client/server application (say in a
supermarket) should be able to survive both a server downtime as well as
a client downtime - implying; that is if I got it correctly; that the
client application (in a retail store for example) should allow the user
to continue selling even if the server should happen to go down.

Somebody please shed some light here. How would I survive a server
downtime if my data (like prices, stock levels etc) are stored in a
Firebird database at the server?
