=head1 NAME

DBIx::Class::Storage::DBI::ODBC::Firebird - Driver for using the Firebird RDBMS
through ODBC

=head1 DESCRIPTION

Most functionality is provided by
L, see that driver for details.

To build the ODBC driver for Firebird on Linux for unixODBC, see:

L

This driver does not suffer from the nested statement handles across commits
issue that the L or the
L based driver does. This
makes it more suitable for long running processes such as under L.
