==History==
Mimer SQL originated from a project from the ITC service center supporting [[Uppsala University]] and some other institutions to leverage the [[relational database]] capabilities proposed by [[Edgar F. Codd|Codd]] and others. The initial release in about 1975 was designated ''RAPID'' and was written in [[Basic assembly language|IBM assembler language]]. The name was changed to ''Mimer'' in 1977 to avoid a trademark issue. Other universities were interested in the project on a number of machine architectures and Mimer was rewritten in [[Fortran]] to achieve portability. Further models were developed for Mimer with the Mimer/QL implementing the [[QUEL query languages]].<ref name="Possible"/>
The emergence of [[SQL]] in the 1980s as the standard query language resulted in Mimers' developers choosing to adopt it with the product becoming ''Mimer SQL''.<ref name="Possible"/>
In 1984 Mimer was transferred to the newly established company ''Mimer Information Systems''.<ref name="Possible"/>
==Versions==
{{As of|July 2025}} the Mimer SQL [[database server]] is currently supported on the main platforms of [[Microsoft Windows|Windows]], [[MacOS]], [[Linux]], [[QNX]], and [[OpenVMS]] ([[Itanium]] and [[x86-64]]<ref>{{cite web|url=https://developer.mimer.com/mimer-sql-is-now-available-for-openvms-on-x86/|title=Mimer SQL is now available for OpenVMS on x86|publisher=Mimer Information Technology AB|date=2023}}</ref>).<ref name="Downer">{{cite web|url=http://developer.mimer.com/downloads/|access-date=10 April 2018|title=Downloads - Mimer SQL - Always free for development!|

The [[enterprise systems|Enterprise]] product is a standards based SQL database server based upon the Mimer SQL Experience database server. This product is highly configurable at build time, and components can be added, removed or replacing in the foundation product to achieve a derived product suitable for embedded, or small footprint application.<ref name="Products">{{cite web|url=http://developer.mimer.com/mimer-sql-overview/|title=The Mimer SQL Products|access-date=10 April 2018|url-status=dead|archive-url=https://web.archive.org/web/20180410162726/http://developer.mimer.com/mimer-sql-overview/|archive-date=10 April 2018}}</ref>
For resource limited environments is the ''Mimer SQL Mobile'' database server a replacement runtime environment without a SQL [[compiler]]. This is used for portable and certain custom devices and is termed the ''Mobile Approach''.<ref name="Products"/> Additionally cancustom [[embedded system|embedded]] approaches be applied to multiple hardware and operating system combinations.<ref name="Products"/>
These options enable Mimer SQL to be deployed to a wide variety of additional target platforms, such as [[Android (operating system)|Android]], and [[real-time operating system]]s including [[QNX]].<ref name="OldPlatforms"/>

Mimer Trust leverages the ARM architecture's TrustZone concept and adds the capability to not only store data inside the TrustZone for added security.
==Features==
Mimer SQL provides support for multiple database application programming interfaces (APIs): [[ODBC]], [[JDBC]], [[ADO.NET]], [[Embedded SQL]] (C/C++, [[COBOL|Cobol]] and Fortran), [[Module SQL]] (C/C++, Cobol, Fortran and Pascal), and the native API's Mimer SQL C API, Mimer SQL Real-Time API, and Mimer SQL Micro C API.▼
