Micro was one of the earliest set theoretic/relational database management systems. Its major underpinnings and algorithms were based on the set-theoretic model of David Childs of the University of Michigan's CONCOMP (Conversational Use of Computers) Project. It was also influenced to a lesser extent by the relational model made famous by Edgar F. Codd, a research scientist at IBM. It used a natural language interface which allowed non-programmers to use the system.
