Regrets, but this is not a Delphi forum.

Try this site: it will answer all your basic n-tier questions and much more!

Treat your database "newbie" issues as one set of skills you need to
develop. This support list will help. It seems you are asking this
because you don't understand transactions. All database operations
in Firebird occur inside transactions. Each transaction is isolated
from all other transactions. The way a transaction is configured
determines whether or not its requests will block (or be blocked
by) other transactions. It's a big and important area of
understanding for working with client/server database services like
Firebird, Oracle, PostGreSQL, etc.

Treat your newness with developing n-tier application architectures
as another, quite separate, but off-topic for this list. Roman, who
kindly responded to your previous question, administers a very lively
list for Java programmers using his Jaybird driver to connect their
Java programs to Firebird. There are other lists around for other
programming languages - see http://firebirdsql.org/index.php?op=lists

A well-thought-out n-tier system is quite neutral about which
database servers it connects to...but this side of your
knowledge-building needs to be developed outside of this support list.
