21、ernational Standards. It provides a set of data quality measures that can be used for measuring and evaluating data quality by referring other SQuaRE series of standards, especially ISO/IEC 25012. The set of data quality measures in this International Standard is selected based on their practical va
22、lue. They are not intended to be exhaustive and users of this International Standard are encouraged to refine them if necessary. Quality measurement division This International Standard is a part of ISO/IEC 2502n series that currently consists of the following International Standards: ISO/IEC 25020
23、Measurement reference model and guide: provides a reference model and guide for measuring the quality characteristics defined in ISO/IEC 2501n. ISO/IEC 25021 Quality measure elements: provides a format for specifying quality measure elements and some examples of quality measure elements that can be
24、used to construct software quality measures. ISO/IEC 25022 Measurement of quality in use: provides measures including associated measurement methods and quality measure elements for the quality characteristics in the quality in use model. ISO/IEC 25023 Measurement of system and software product qual
25、ity: provides measures including associated measurement methods and quality measure elements for the quality characteristics in the product quality model. ISO/IEC 25024 Measurement of data quality: provides measures including associated measurement methods and quality measure elements for the qualit
26、y characteristics in the data quality model. Figure 1 depicts the relationship between this International Standard and the other standards in ISO/IEC 2502n.

27、 organization of SQuaRe series The SQuaRE series consists of five main divisions and extension division. Outline of each divisions within SQuaRE series are as follows. ISO/IEC 2500n Quality Management Division. The standards that form this division define all common models, terms, and definitions re
28、ferred further by all other standards from SQuaRE series. The division also provides requirements and guidance for the planning and management of a project. ISO/IEC 2501n Quality Model Division. The standards that form this division present quality models for system/software products, quality in use
29、, and data. A service quality is under development. Practical guidance on the use of the quality model is also provided. ISO/IEC 2502n Quality Measurement Division. The standards that form this division include a system/software product quality measurement reference model, definitions of quality mea
30、sures, and practical guidance for their application. This division presents internal measures of software quality, external measures of software quality, quality in use measures, data quality measures from “Inherent”, and “System dependent” point of view. Quality measure elements forming foundations
31、 for the quality measures are defined and presented. ISO/IEC 2503n Quality Requirements Division. The standards that form this division help specify quality requirements. These quality requirements can be used in the process of quality requirements elicitation for a system/software product to be dev
32、eloped designing a process for achieving necessary quality or as inputs for an evaluation process. ISO/IEC 2504n Quality Evaluation Division. The standards that form this division provide requirements, recommendations, and guidelines for system/software product evaluation whether performed by indepe
33、ndent evaluators, acquirers, or developers. The support for documenting a quality measure as an evaluation module is also presented. ISO/IEC 25050 to ISO/IEC 25099 are reserved for SQuaRE extension International Standards which currently includes ISO/IEC 25051 and ISO/IEC 25060 to ISO/IEC 25069.vi I

35、itatively measuring the data quality in terms of characteristics defined in ISO/IEC 25012. This International Standard contains the following: a basic set of data quality measures for each characteristic; a basic set of target entities to which the quality measures are applied during the data-life-c
36、ycle; an explanation of how to apply data quality measures; a guidance for organizations defining their own measures for data quality requirements and evaluation. It includes, as informative annexes, a synoptic table of quality measure elements defined in this International standard (Annex A), a tab
37、le of quality measures associated to each quality measure element and target entitiy (Annex B), considerations about specific quality measure elements (Annex C), a list of quality measures in alphabetic order (Annex D), and a table of quality measures grouped by characteristics and target entities (
38、Annex E). This International Standard does not define ranges of values of these quality measures to rate levels or grades because these values are defined for each system by its nature depending on the system context and users needs. This International Standard can be applied to any kind of data ret
39、ained in a structured format within a computer system used for any kinds of applications. People managing data and services including data are the primary beneficiaries of the quality measures. This International Standard is intended to be used by people who need to produce and/or use data quality m
40、easures while pursuing their responsibilities. Acquirer (an individual or organization that acquires or procures data from a supplier). Evaluator (an individual or organization that performs an evaluation, which can, for example, be a testing laboratory, the quality department of an organization, a
41、government organization, or a user). Developer (an individual or organization that performs development activities including requirements, analysis, design, implementation, and testing data during the data-life-cycle). Maintainer (an individual or organization that performs operation and maintenance
42、 activities of data). Supplier (an individual or organization that enters into a contract with the acquirer for the supply of data or service under the terms of the contract). User (an individual or organization that uses data to perform a specific function). Quality manager (an individual or organi
43、zation that performs a systematic examination of the data). Owner (an individual or organization that takes responsibility for the management and financial value of the data with the legal authority and responsibility to establish for them evaluation, collections, access, dissemination, storage, sec
44、urity, and cancellation). ISO/IEC 2015 All rights reserved 1BS ISO/IEC 25024:2015ISO/IEC 25024:2015(E) This International Standard takes into account a large range of data of target entities. It can be applied in many types of information systems, for example, such as follows: legacy information sys
45、tem; data warehouse; distributed information system; cooperative information system; world wide web. The scope does not include the following: knowledge representation; data mining techniques; statistical significance for random sample. 2 Conformance Any measurement process for requirement, implemen
46、tation, or evaluation of data quality shall be conformed to this International Standard: a) selecting data quality characteristics to be specified or evaluated as defined in ISO/IEC 25012; b) selecting a target entity for which data quality characteristic shall be measured; c) selecting the appropri
47、ate data quality measures defined in Clause 8 by each data quality characteristic concerning a target entity; d) providing the rationale for any changes when modify the data quality measures; e) listing any additional quality measures or quality measure elements used that are not included in this In
48、ternational Standard. Order of items a) and b) can be applied in reverse. When using modified or new data quality measures, the user shall specify the target entities, measurement method, and related data quality characteristics of ISO/IEC 25012 or specifying any other data quality model that is bei
49、ng used. This International Standard does not provide a complete list of quality measure related to data defined during the data-life-cycle. The user may also identify some other quality measures depending on the technology applied. Even if a number of quality measures included in this International Standard have not been empirically validated and some of them are not based yet on best practice
