13 =head1 DESCRIPTION
14
15 Most functionality is provided by L<DBIx::Class::Storage::DBI::Interbase>, see
16 that module for details.
17
18 To build the ODBC driver for Firebird on Linux for unixODBC, see:
19
20 L<http://www.firebirdnews.org/?p=1324>
21
22 This driver does not suffer from the nested statement handles across commits
23 issue that the L<DBD::InterBase|DBIx::Class::Storage::DBI::InterBase> based
24 driver does. This makes it more suitable for long running processes such as
25 under L<Catalyst>.
