OpenQM is a MultiValue database originally developed by Ladybridge Systems in the United Kingdom and subsequently acquired by Zumasys.
It was released as a full featured runtime and development environment in 2001, initially for Windows and subsequently for Linux.
In late 2008, a community-driven site formed to direct a fork of the GPL release named ScarletDME.
The database products owned by Zumasys (OpenQM and jBASE) were sold to Rocket Software in October 2021.
This functionality makes creation, parsing or processing of JSON strings very easy, simplifying web development.
