Open Query was founded by Arjen Lentz, a member of the Australian free and open source community, nearly 11 years ago.
MySQL is now a part of Oracle after the company acquired Sun Microsystems in 2010. MariaDB is a fork of MySQL and is run by Monty Widenius, one of the original quartet who created MySQL.
Catalyst is a company that was started in New Zealand in 1997 and is an experienced open source integrator.
Lentz said: “Catalyst’s core values are very much aligned with those of Open Query, which is why we are particularly pleased with this outcome.”
Catalyst has offices in Sydney, Melbourne and Brisbane.
