The family of Integrated Definition Languages
, short IDEF, were first developed in the 1970s
and are standard modelling techniques nowadays. They cover a range of applications from function modelling to information, simulation, object-oriented analysis and design and knowledge acquisition. Specifically, IDEF(0) is a functional modelling language building on SADT, and IDEF(1x) addresses information models. IDEF(1x) was created by the U.S. Air Force
based on ERDs.
