7、mber bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governme
8、ntal and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenanc
9、e are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives). Attent
10、ion is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction
11、and/or on the ISO list of patent declarations received (see www .iso .org/ patents). Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.

13、 ISO/TC 184, Automation systems and integration, Subcommittee SC 4, Industrial data. This second edition cancels and replaces the first edition (ISO 8000-2:2012), which has been technically revised, with the addition and modification of some terms and definitions. ISO 8000 is organized as a series o
14、f parts, each published separately. The structure of ISO 8000 is described in ISO/TS 8000-1. Each part of ISO 8000 is a member of one of the following series: general data quality, master data quality and product data quality. This document is a member of the general data quality series but applicab
15、le to all of the three data quality series. A list of all parts in the ISO 8000 series can be found on the ISO website.iv ISO 2017 All rights reserved ISO 8000-2:2017(E) Introduction The ability to create, collect, store, maintain, transfer, process and present data to support business processes in
16、a timely and cost effective manner requires both an understanding of the characteristics of the data that determine its quality, and an ability to measure, manage and report on data quality. ISO 8000 defines characteristics that can be tested by any organization in the data supply chain to objective
17、ly determine conformance of the data to ISO 8000. ISO 8000 provides frameworks for improving data quality for specific kinds of data. The frameworks can be used independently or in conjunction with quality management systems. ISO 8000 covers industrial data quality characteristics throughout the pro
18、duct life cycle from conception to disposal. ISO 8000 addresses specific kinds of data including, but not limited to, master data, transaction data and product data. This document establishes the vocabulary for the ISO 8000 series of parts. Annex A contains an identifier that unambiguously identifie
19、s this document in an open information system.
