MSQL

Mini SQL (mSQL) is a relational database management system from Hughes Technologies.

History

The database to feature a SQL interface but sported a flat file back end rather than a true relational file set. Very popular in the 90s as a web back end but gave way to MySQL and SQLite due to licensing issues. The original author David Hughes still supports the product commercially and provides occasional updates, but no one has bothered to port the more recent versions as better alternatives are available.
