I notice there are many components for writing applications for firebird, but
most of them are for window only and more often for Delphi. There are Linux
admin tools but you can not write applications using them.

But it appears firebird is also widely installed under linux/unix. I am curious
how applications are written for linux/firebird. Do they use embedded sql or
call isc_ api directly? Or use jdbc? or just as a remote database server
listening to tcp/ip ports?
