=head1 NAME

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

=head1 DESCRIPTION

Most functionality is provided by
L<DBIx::Class::Storage::DBI::Firebird::Common>, see that driver for details.

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

L<http://www.firebirdnews.org/?p=1324>

This driver does not suffer from the nested statement handles across commits
issue that the L<DBD::InterBase|DBIx::Class::Storage::DBI::InterBase> or the
L<DBD::Firebird|DBIx::Class::Storage::DBI::Firebird> based driver does. This
makes it more suitable for long running processes such as under L<Catalyst>.
