11、10 All rights reserved IEEE 2010 All rights reserved vForeword ISO (the 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
12、 development of International Standards through technical committees established 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-gov
13、ernmental, in liaison with ISO and IEC, also take part in the work. In 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
14、Standards Association (IEEE-SA) Standards Board. The IEEE develops its 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
15、not necessarily members of the Institute and serve without compensation. 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 i
16、n its standards. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of ISO/IEC JTC 1 is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies fo
17、r 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 implementation of this standard may require the use of subject matter covered by patent rights. By publication of this standard, no
18、 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 patent claims for which a license may be required, for conducting inquiries into the legal validity or scope of patents or paten
19、t 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 Form, if any, or in any licensing agreements are reasonable or non-discriminatory. Users of this standard are expressly ad
20、vised that determination of the validity of any patent rights, and the risk of infringement of such rights, is entirely their own responsibility. Further information may be obtained from ISO or the IEEE Standards Association. ISO/IEC/IEEE 24765 was prepared by Joint Technical Committee ISO/IEC JTC 1
21、, Information technology, Subcommittee SC 7, Software and systems engineering, in cooperation with the Software company proprietary or trademarked; multi-word terms whose meaning could be inferred from the definitions of the component words; terms whose meaning in the information technology (IT) fie
22、ld could be directly inferred from their common English meaning. 1.1 Relationship of the print and internet-accessible versions The primary tool for maintaining this vocabulary is a database that is modified in a controlled fashion. Hosted by the IEEE Computer Society, the SEVOCAB (systems and softw
23、are engineering vocabulary) database is publicly accessible at puter.org/sevocab. ISO/IEC 24765 is issued periodically as a formal, published International Standard reflecting a “snapshot“ of the database. The copyright notice provided with the database permits users to copy definitions from the dat
24、abase as long as the source of the definition is cited. Permitting public use of the definitions in the database is intended to encourage the use of other ISO/IEC JTC 1 and IEEE systems and software engineering standards. 1.2 Vocabulary structure Entries in the vocabulary are arranged alphabetically
25、. Blanks precede all other characters in alphabetizing. Hyphens and slashes (- and /) follow all other characters in alphabetizing. An entry can consist of a single word, such as “software“; a phrase, such as “test case“; or an acronym, such as “CDR“. Phrases are given in their natural order (test p
26、lan) rather than in reversed order (plan, test). Acronyms can be listed separately as well as in parentheses following the source term. Terms that are verbs are shown without the infinitive marker “to“. After each term, numbered definitions are listed in order of preference, or from the most general
27、 to the more specific usages. The different definitions can show the use of a term as a noun, verb and adjective. This International Standard includes references to the active source standards for each definition, so that the use of the term can be further explored. The sources of most of the defini
28、tions are ISO JTC 1/SC 7 or IEEE Computer Society standards and the PMI Glossary, Fourth Edition. Sources are listed in Annex A. In some ISO/IEC/IEEE 24765:2010(E) 2 ISO/IEC 2010 All rights reserved IEEE 2010 All rights reservedcases, the same definition can also be found in other active or withdraw
29、n standards. No source is shown if the original source standard has been withdrawn or archived and the definition has been retained in this vocabulary. Notes (comments), Examples, and illustrations taken from the source standards have been included to clarify selected definitions. The following cros
30、s-references are used to show a terms relationship to other terms in the dictionary. Syn refers to a synonym: a term with the same meaning. Synonyms are listed under the preferred term and can be located by searching. cf. refers to related terms that are not synonyms. 1.3 PMI Glossary provisions The
31、 Project Management Institute (PMI) Glossary definitions have been included without alteration in accordance with the copyright agreement. Many of these definitions include explanatory material. For other terms and other definitions that have ISO/IEC and IEEE standards as their source, explanatory m
32、atter is shown in the Notes and Examples. Many of the definitions from the PMI Glossary begin with a word or phrase in brackets, such as Process, Output/Input, Technique. These bracketed entries refer to the schema of the Project Management Institute, A Guide to the Project Management Body of Knowle
33、dge (PMBOK1)Guide) Fourth Edition, which provides further explanation. 2 Conformance The definitions in this International Standard are drawn from normative standards and informative guidance documents, including ISO Technical Reports (TR). This International Standard may be used as a normative docu
34、ment for projects and organizations claiming conformance to the normative source standards. Where terms have multiple definitions, users should consult the source standards for further information on appropriate usage within a specific context. Annex B lists other references. Terms, definitions, and
35、 notes use spelling preferred in the USA. The use of capital letters has been minimized and generally limited to proper names and acronyms. In some cases the source standard uses another correct spelling (such as behaviour rather than behavior, on-line rather than online). Other correct spellings an
36、d capitalization of the terms, according to a national standard, an authoritative general dictionary or accepted style guide may be used with the definitions. 3 Terms and definitions 3.1 language 1. definitions of concepts and rules for the specification of an ODP system from the viewpoint.
