It provides a set of data quality measures that can be used for me

21、asuring 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 value. They are not intended to be exhaustive and users of this International Standard are

22、encouraged to refine them if necessary.Quality measurement divisionThis International Standard is a part of ISO/IEC 2502n series that currently consists of the following International Standards: ISO/IEC 25020 Measurement reference model and guide: provides a reference model and guide for measuring t

23、he 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 used to construct software quality measures. ISO/IEC 25022 Measurement of quality in use: p

24、rovides 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 quality: provides measures including associated measurement methods and quality measure element

25、s 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 quality characteristics in the data quality model.Figure 1 depicts the relationship between this

27、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 referred further by all other standards from SQuaRE series. The division also provides requiremen

28、ts 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, and data. A service quality is under development. Practical guidance on the use of the qualit

29、y 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 measures, and practical guidance for their application. This division presents internal measures o

30、f 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 for the quality measures are defined and presented. ISO/IEC 2503n Quality Requirements Divisio

31、n. 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 developed designing a process for achieving necessary quality or as inputs for an evaluation proce

32、ss. 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 independent evaluators, acquirers, or developers. The support for documenting a quality measure as an

33、 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 ISO/IEC 2015 All rights reservedBS ISO/IEC 25024:2015INTERNATIONAL STANDARD ISO/IEC 25024:2015(E)

34、Systems and software engineering Systems and software Quality Requirements and Evaluation (SQuaRE) Measurement of data quality1 ScopeThis International Standard defines data quality measures for quantitatively measuring the data quality in terms of characteristics defined in ISO/IEC 25012.This Inter

35、national 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-cycle; an explanation of how to apply data quality measures; a guidance for organizations defining the

36、ir 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 table of quality measures associated to each quality measure element and target entitiy (Annex B), consid

37、erations 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 (Annex E).This International Standard does not define ranges of values of these quality measures to rat

38、e 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 retained in a structured format within a computer system used for any kinds of applications.People managing

39、 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 measures while pursuing their responsibilities. Acquirer (an individual or organization that acquires or pr

40、ocures 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 government organization, or a user). Developer (an individual or organization that performs development ac

41、tivities including requirements, analysis, design, implementation, and testing data during the data-life-cycle). Maintainer (an individual or organization that performs operation and maintenance activities of data). Supplier (an individual or organization that enters into a contract with the acquire

42、r 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 organization that performs a systematic examination of the data). Owner (an individual or organization that take

43、s 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, security, and cancellation). ISO/IEC 2015 All rights reserved 1BS ISO/IEC 25024:2015ISO/IEC 25024:2015(E)This

44、 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 system; data warehouse; distributed information system; cooperative information system; world wide web.The scop

45、e does not include the following: knowledge representation; data mining techniques; statistical significance for random sample.2 ConformanceAny measurement process for requirement, implementation, or evaluation of data quality shall be conformed to this International Standard:a) selecting data quali

46、ty 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 appropriate data quality measures defined in Clause 8 by each data quality characteristic concerning a target entity;d) pr

47、oviding 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 International Standard.Order of items a) and b) can be applied in reverse.When using modified or new data quality meas

48、ures, 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 being used. This International Standard does not provide a complete list of quality measure related to data defined durin

49、g 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 practices observed in industry, this International Standard is still a good base and an opportunity to improve the data quality measures.3 Normative referencesThe following documents, in whole or in part, ar
