DBIx::Class::Storage::DBI::ODBC::Firebird - Driver for using the Firebird RDBMS
through ODBC
-=head1 SYNOPSIS
+=head1 DESCRIPTION
-All functionality is provided by L<DBIx::Class::Storage::DBI::Interbase>, see
+Most functionality is provided by L<DBIx::Class::Storage::DBI::Interbase>, see
that module 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> based
+driver does. This makes it more suitable for long running processes such as
+under L<Catalyst>.
