[edit] OpenQM history
OpenQM was first released in developed in 1993 as an in-house embedded database. It was finally released as a full featured run-time and development environment in 2001. In 2004 an open-source General Public Licence version was released for Linux.
OpenQM is dual-licensed, much like MySQL. This allows open-source applications to freely use the software under the GPL, while still allowing commercial users the flexibility of a commercial license.
[edit] Unique Multi-Value features
OpenQM is a multivalue database, and, as such, shares many aspects in common with similar Pick-decended databases. It also has a number of unique features not found in other commercial MV databases, such as auto-sizing of database files, 'binary clean' execution of QMBasic, and, perhaps uniquely in the MV world, object and class support in Basic.
