9、International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees est
10、ablished by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non- governmental, in liaison with ISO and IEC, also take part in the work. In
11、the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its
12、standards through a consensus development process, approved by the American National Standards Institute, which brings together volunteers representing varied viewpoints and interests to achieve the final product. Volunteers are not necessarily members of the Institute and serve without compensation
13、. While the IEEE administers the process and establishes rules to promote fairness in the consensus development process, the IEEE does not independently evaluate, test, or verify the accuracy of any of the information contained in its standards. The main task of ISO/IEC JTC 1 is to prepare Internati
14、onal Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is called to the possibility that implemen
15、tation of this standard may require the use of subject matter covered by patent rights. By publication of this standard, no position is taken with respect to the existence or validity of any patent rights in connection therewith. ISO/IEEE is not responsible for identifying essential patents or paten
16、t claims for which a license may be required, for conducting inquiries into the legal validity or scope of patents or patent claims or determining whether any licensing terms or conditions provided in connection with submission of a Letter of Assurance or a Patent Statement and Licensing Declaration

Members of the
30、committees serve voluntarily and without compensation. They are not necessarily members of the Institute. The standards developed within IEEE represent a consensus of the broad expertise on the subject within the Institute as well as those activities outside of IEEE that have expressed an inter- est
31、 in participating in the development of the standard. Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE Standard.
32、 Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to change brought about through developments in the state of the art and comments received from users of the standard. Every IEEE Standard is sub- jected to review at least every ve years for revision or r
33、eafrmation. When a document is more than ve years old and has not been reafrmed, it is reasonable to conclude that its contents, although still of some value, do not wholly reect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE Sta
34、ndard. Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership afliation with IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Interpretations: Occasionally qu
35、estions may arise regarding the meaning of portions of standards as they relate to specic applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards rep- resent a consensus of all conc
36、erned interests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason, IEEE and the members of its societies and Standards Coordinating Committees are not able to provide an instant response to interpretation requests except i
37、n those cases where the matter has previously received formal consideration.

42、 a part of IEEE Std 1320.2-1998, IEEE Standard for Conceptual Modeling Language Syntax and Semantics for IDEF1X 97 (IDEF object ). Background The need for semantic models to represent conceptual schemas was recognized by the US Air Force in the mid 1970s as a result of the Integrated Computer Aided
43、Manufacturing (ICAM) Program. The objective of this program was to increase manufacturing productivity through the systematic application of computer technology. The ICAM program identied a need for better analysis and communication techniques for peo- ple involved in improving manufacturing product
44、ivity. As a result, the ICAM program developed a series of techniques known as the ICAM Denition (IDEF) methods, which included the following: a) IDEF0, a technique used to produce a “function model,” which is a structured representation of the activities or processes within the environment or syste
45、m. b) IDEF1, a technique used to produce an “information model,” which represents the structure and semantics of information within the environment or system. c) IDEF2, a technique used to produce a “dynamics model,” which represents the time-varying behav- ioral characteristics of the environment o
46、r system. IDEF0 and IDEF1X (the successor to IDEF1) continue to be used extensively in various government and industry settings. IDEF2 is no longer used to any signicant extent. The initial approach to IDEF information modeling (IDEF1) was published by the ICAM program in 1981, based on current rese
47、arch and industry needs B23. 1The theoretical roots for this approach stemmed from the early work of Dr. E. F. Codd on relational theory and Dr. P. P. S. Chen on the entity-relationship model. The initial IDEF1 technique was based on the work of Dr. R. R. Brown and Mr. T. L. Ramey of Hughes Air- cra
48、ft and Mr. D. S. Coleman of D. Appleton Company, with critical review and inuence by Mr. C. W. Bach- man, Dr. P. P. S. Chen, Dr. M. A. Melkanoff, and Dr. G. M. Nijssen. In 1983, the US Air Force initiated the Integrated Information Support System (I 2 S 2 ) project under the ICAM program. The object
49、ive of this project was to provide the enabling technology to integrate a network of het- erogeneous computer hardware and software both logically and physically. As a result of this project and industry experience, the need for an enhanced technique for information modeling was recognized. Application within industry had led to the development in 1982 of a Logical Database Design Technique (LDDT) by R. G. Brown of the Database Design Group. The technique was also based on the relational model of Dr. E. F. Codd and the entity-relationship mod
