IDEF, initially abbreviation of ICAM Definition, refers to a family of modeling languages in the field of systems and software engineering. It is initiated in the 1970s at the US Air Force Materials Laboratory, Wright-Patterson Air Force Base in Ohio by Dennis E. Wisnosky, Dan L. Shunk and others. IDEF covers a wide range of uses, from functional modeling to data, simulation, object-oriented analysis and design as well as knowledge acquisition.
There are many types of IDEF diagrams including IDEF0, IDEF1, IDEF1X, IDEF2, IDEF3, IDEF4, IDEF5, IDEF6, IDEF7, IDEF8, IDEF9, IDEF10, IDEF11, IDEF12, IDEF13 and IDEF14.
