'''Mimer SQL''' is an [[SQL]]-based [[relational database management system]] from the [[Sweden|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 [[Mímir|Mimer]] was the giant guarding the well of wisdom, also knows as "[[Mímisbrunnr]]". Metaphorically is this what Mimer SQL does - manages data.

Mimer SQL offers a scalable and portable solution providing [[database server]]s for environments that spans from [[embedded systems|embedded]] and [[real-time operating systems]] to [[enterprise systems]]. This includes platforms like [[Microsoft Windows|Windows]], [[MacOS]], [[Linux]], [[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>

Mimer SQL uses [[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>.

Some of the main characteristics for Mimer SQL are high performance, small [[memory footprint]] and a low level of maintenance.<ref name="footprint">{{bokref | title = Mimer SQL Technical Description | url = http://developer.mimer.com/documentation/WhitePapers/Technical_Description/MIMTECDESC.pdf | format = [[Portable Document Format|PDF]] | author= Mimer Information Technology | chapter = Technical Benefits Overview}}</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.

Mimer SQL uses [[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> which provides a solution to the problem of allowing simultaneous access to the database without the danger of a [[deadlock]] occurring.<ref name="transaction-management">{{webbref | url = http://developer.mimer.se/features/feature_12.htm/ | title = Transaction Management | work = Mimer Developers – Features | date = 5 May 2017}}</ref> This may simplify database management and allow truly scalable performance, even during heavy system load.

Another technical issue is the data storage mechanism, which in Mimer SQL is implemented to be constantly optimized for maximum performance. This also ensures that no manual reorganization of the database is ever needed.<ref name="data-storage">{{webbref | url = http://developer.mimer.se/features/feature_11.htm/ | title = Data Storage in Mimer SQL | work = Mimer Developers – Features | date = 5 May 2017}}</ref>

The database management language Mimer SQL ([[Structured Query Language]]) is compatible in all essential features with the currently accepted SQL standards.<ref name="standard-sql">{{webbref | url = http://developer.mimer.se/standard/ | title = Mimer SQL Standard Compliance | work = Mimer Developers – SQL Standard | date = 5 May 2017}}</ref>
