This section drafted in accordance with GB/T 1.1-2009 given rules.

This section uses redrafted law revision using ISO/IEC 25024:2015 "system and software engineering systems and software quality requirements and Evaluation (SQuaRE) Data Quality Measurement ", compared with ISO/IEC 25024:2015, the main technical differences and their reasons are as follows.

--- Normative references, with the revision of the international standard GB/T 25000.12-2017 instead of ISO/IEC 25012.

2008, to adapt to our country's technical conditions.

This section made the following editorial changes.

--- Modify the standard name;

--- Removed the scope of the list repeatedly appendix content description, but keep 8.1 in the appendix of instructions;

--- Figure 2, the "measurement" is corrected as "by measurement", "definition" to correct "by definition", and, in order to facilitate understanding, by Add "Generate" "Measure by" "Include" and other processes described.

--- In order to reflect the characteristics of Appendix D in alphabetical order, add a column to the far left of Table D.1, fill in the quality measure of English name.

Introduction

This section is part of the SQuaRE family of standards. It provides a data quality measure set by reference to the SQuaRE series Other standards (especially GB/T 25000.12-2017) can be used to measure and evaluate data quality.

The data quality measure set in this section was chosen based on its value in practice. The intent of these data quality measures is not is exhaustive; users in this section are encouraged to refine them if necessary.

Quality Measurement Division this section is GB/T 25000SQuaRE series of standard part of the quality measurement division. ISO/IEC 2502n quality measurement points the Department currently includes the following criteria.

--- ISO/IEC 25020 Measurement Reference Model and Guidance. To measure the quality defined in the ISO/IEC 2501n Quality Model Division the quantity features provide reference models and guidelines.

--- ISO/IEC 25021 quality measurement elements. Provide the format used to specify the quality measurement elements, and can be used to build the software quality an example of a measure of the quality measure element.

--- ISO/IEC 25022 use of quality measurement. Provide measurement, including the associated measurement methods and the use of quality model quality Characteristics of the quality measurement element.

--- ISO/IEC 25023 system and software product quality measurement. Provide measures, including the associated measurement methods and product quality Quality measure of quality characteristics in the model.

--- ISO/IEC 25024 data quality measurement. Provide measures, including the associated measurement methods and data quality model quality Characteristics of the quality measurement element.

Figure 1 depicts the relationship between the various standards in the ISO/IEC 2502n Quality Measurement Division.

Figure 1 Quality Measurement Division structure

SQuaRE series of international standards overview and organization the SQuaRE series of international standards consists of five main and expansion divisions. An overview of each division in the SQuaRE series of standards is as follows.

--- ISO/IEC 2500n. Quality Management Division. The criteria that make up this division are defined by the SQuaRE family of standards all other public reference standards, terms and definitions. This division also provides for the planning and management of a project Needs and guidelines.

--- ISO/IEC 2501n. Quality Model Division. The criteria that make up this division are quality of use, data, and system or software products Provided the quality model. Quality of service is under development. A practical guide to using this quality model is also provided.

--- ISO/IEC 2502n. Quality Measurement Division. The standards that make up this division include reference models for quality measurement of systems and software products Type, the definition of quality measure and its practical guide. This section gives the system and software product quality measurement, quality of use Measurement as well as data quality measurements for "native" and "system dependent" viewpoints. Define and give the composition quality measure Basic quality measure element.

--- ISO/IEC 2503n. Quality Requirements Division. The criteria that make up this division help users set quality requirements. These quality wants Seek to be used in the quality requirements extraction process for a system or software product to be developed (to design a process that achieves the necessary quality) or Used as input to the evaluation process.

--- ISO/IEC 2504n. Quality Evaluation Division. The criteria that make up this division are given by independent evaluators, by demand side, or by Requirements, Recommendations and Guidelines for Evaluation of Systems or Software Products Implemented by Developers. Also given as a measure of the quality of the module Compilation support.

ISO/IEC 25050 ~ ISO/IEC 25099 is reserved for use with SQuaRE to expand international standards, currently including ISO/IEC 25051 and ISO/IEC 25060 ~ ISO/IEC 25069.

Systems and software engineering systems and software quality Requirements and Evaluation (SQuaRE) Part 24. Data quality measurement

1 Scope

GB/T 25000 defined in this part of the data quality measures for the characteristics defined in GB/T 25000.12-2017 to quantify to measure data quality.

This section contains.

--- A basic set of data quality measures for each characteristic;

--- Basic set of target entities to which quality measures have been applied in the data life cycle;

--- Explain how to apply data quality measures;

--- Guiding organizations to define their own data quality needs and evaluation of the measure.

This section does not define the range of values or ratings for these measures of quality as these values are based on system context and Different user needs, respectively, for each of the different characteristics of the system definition.

This section applies to any type of data in a structured format for use in any type of computer system.

People who manage data and focus on data services are the main beneficiaries of these quality measures.

This section is intended for those who need to produce and/or use the data quality measures used in fulfilling their responsibilities. These people include.

--- Demand side (individuals or organizations that obtain or obtain data from suppliers);

--- Evaluation side (executive evaluation of individuals or organizations. Evaluation side can be a test laboratory, an organization's quality department, a Government agency or a user);

--- Development side (implementation development activities --- including the definition of demand in the data life cycle, analysis, design, implementation and test data Person or organization);

--- maintenance side (the person or organization that performs the operation and maintenance activities of the data);

--- supplier (under the terms of the contract, the supply of data or services and demand-side contract between the performance of individuals or organizations);

--- users (individuals or organizations that use data to implement specific functions);

--- Quality managers (individuals or organizations that systematically inspect data);

--- Owner (responsible for data management and economic value, for data evaluation, collection, access, dissemination, storage, security and Cancel a person or organization that owns legal rights and responsibilities).

This section considers a wide range of target entity data.

It can be applied to many types of information systems, as shown below.

--- legacy information system;

---database;
