Mimer SQL is an SQL-based relational database management system  from the Swedish company Mimer Information Technology AB (formerly Upright Database Technology AB). It has been developed and produced since the 1970s when it was founded at the Uppsala University, Uppsala, Sweden.
The name "Mimer" is taken from the Norse mythology, where Mimer was the giant guarding the well of wisdom, also knows as "Mímisbrunnr". Metaphorically this is what a database system is doing - managing data.
Mimer SQL offers a scalable and portable solution providing database servers for environments that spans from embedded and real-time operating systems to enterprise systems. This includes platforms like Windows, MacOS, Linux, Android, Unix, OpenVMS, and VxWorks.
