Data Quality is the process of assessing, monitoring, and improving the fitness of an organizations data for business use. Fitness is generally a measure of the accuracy, completeness, accessibility, and timeliness of data. Data quality includes capabilities for processing data (integration, parsing, cleansing, matching, etc.) and for assessing data (monitoring, profiling, reporting). Data Quality is also closely related to Data Governance (metadata, security / privacy / compliance, performance, etc.).
Data Quality is used by an organization to understand and improve outcomes that depend on high-quality data, such as customer experience or supply-chain management.
