ISO/IEC 25012:2008 defines a general data quality model for data retained in a structured format within a computer system. ISO/IEC 25012:2008 can be used to establish data quality requirements, define data quality measures, or plan and perform data quality evaluations. It could be used, for example, to define and evaluate data quality requirements in data production, acquisition and integration processes, to identify data quality assurance criteria, also useful for re-engineering, assessment and improvement of data, to evaluate the compliance of data with legislation and/or requirements. ISO/IEC 25012:2008 categorizes quality attributes into fifteen characteristics considered by two points of view: inherent and system dependent. Data quality characteristics will be of varying importance and priority to different stakeholders. ISO/IEC 25012:2008 is intended to be used in conjunction with the other parts of the SQuaRE series of International Standards, and with ISO/IEC 9126-1 until superseded by ISO/IEC 25010.
