IDEF

IDEF originally stood for ICAM Definition and is a set of modeling languages ​​, which were published in the early 1980s. Meanwhile IDEF is usually advertised as Integrated definition. The IDEF languages ​​were developed in the ICAM- project of the U.S. Air Force. As these languages ​​on the one hand and on the other hand American authorities standard open (ie freely usable and neutral and therefore independent of the manufacturer ), they were assisted within a short period of CASE tools.
