IDEF
IDEF, initially an abbreviation of ICAM Definition and renamed in 1999 as Integration Definition, is a family of modeling languages in the field of systems and software engineering. They cover a wide range of uses from functional modeling to data, simulation, object-oriented analysis and design, and knowledge acquisition. These definition languages were developed under funding from U.S. Air Force and, although still most commonly used by them and other military and United States Department of Defense (DoD) agencies, are in the public domain.
The most-widely recognized and used components of the IDEF family are IDEF0, a functional modeling language building on SADT, and IDEF1X, which addresses information models and database design issues.
IDEF refers to a family of modeling language, which cover a wide range of uses, from functional modeling to data, simulation, object-oriented analysis/design and knowledge acquisition. Eventually the IDEF methods have been defined up to IDEF14:
In 1995 only the IDEF0, IDEF1X, IDEF2, IDEF3 and IDEF4 had been developed in full. Some of the other IDEF concepts had some preliminary design. Some of the last efforts were new IDEF developments in 1995 toward establishing reliable methods for business constraint discovery IDEF9, design rationale capture IDEF6, human system, interaction design IDEF8, and network design IDEF14.
The methods IDEF7, IDEF10, IDEF11, IDEF 12 and IDEF13 haven't been developed any further than their initial definition.
IDEF originally stood for ICAM Definition, 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. and completed in the 1980s. IDEF was a product of the ICAM initiative of the United States Air Force. The IEEE recast the IDEF abbreviation as Integration Definition."
The specific projects that produced IDEF were ICAM project priorities 111 and 112 (later renumbered 1102). The subsequent Integrated Information Support System (IISS) project priorities 6201, 6202, and 6203 attempted to create an information processing environment that could be run in heterogeneous physical computing environments. Further development of IDEF occurred under those projects as a result of the experience gained from applications of the new modeling techniques. The intent of the IISS efforts was to create 'generic subsystems' that could be used by a large number of collaborating enterprises, such as U.S. defense contractors and the armed forces of friendly nations.
At the time of the ICAM 1102 effort there were numerous, mostly incompatible, data model methods for storing computer data — sequential (VSAM), hierarchical (IMS), network (Cincom's TOTAL and CODASYL, and Cullinet's IDMS). The relational data model was just emerging as a promising way of thinking about structuring data for easy, efficient, and accurate access. Relational database management systems had not yet emerged as a general standard for data management.
