'''Mimer SQL''' is an [[SQL]]-based [[relational database management system]] from the [[Sweden|Swedish]] company ''Mimer Information Technology AB'' (formerly ''Upright Database Technology AB'')., Itwhich has been developed and produced since the 1970s. whenMimer itSQL wasoffers foundeda atscalable theand portable solution and provide servers for environments that spans from [[Uppsalaembedded Universitysystems|embedded]] and [[real-time operating systems]] to [[enterprise systems]]. This includes platforms like [[Microsoft Windows|Windows]], [[UppsalaMacOS]], [[SwedenLinux]], [[Android]], [[Unix]], [[OpenVMS]], and [[VxWorks]] <ref name="platforms">{{webbref | url = http://developer.mimer.com/platforms/index.tml | title = Mimer SQL Products & Platforms | work = Mimer Developers – Platforms | date = 5 May 2017}}</ref>. Unlike other competing DBMSes, Mimer SQL only implements [[optimistic concurrency control]] (OCC) <ref>{{cite web | url = http://developer.mimer.com/features/feature_15.htm | title = Transaction Concurrency - Optimistic Concurrency Control | work = Mimer Developers - Features | date = 26 February 2010}}</ref>.

These attributes are based on a number of technical solutions to handle some of the more complicated functionality that a database management system must provide. ▼The name "Mimer" is taken from the [[Norse mythology]], where [[Mímir|Mimer]] was the giant guarding the well of wisdom, also knows as "[[Mímisbrunnr]]". Metaphorically is this what Mimer SQL does - manages data.
