'''Micro''' was one of the earliest relational [[database management system]]s. It was originally implemented in 1968 at the [[University of Michigan]],. It became the first large scale relational database management system to be used in production. Organizations such as the US Department of Labor, the Environmental Protection Agency and researchers from University of Alberta, the University of Michigan and Wayne State University used it to manage very large scale databases. It ran under [[Michigan Terminal System]]. It combined the relational model later made famous by [[Edgar F. Codd]] and [[Michael Stonebraker]] of the University's Database Research Group with a natural language interface which allowed non-programmers to use the system.
