• Data ownerA data owner is the senior business person accountable for a defined set of data: its definition, quality standards, access rules and fitness for use. The owner approves changes and remediation priorities, while data stewards do the day-to-day work.
• Data quality ruleA data quality rule is an automated test that checks data against an expectation, for example that a maturity date follows the trade date or that a mandatory field is filled. Each rule maps to a quality dimension and has a threshold, an owner and an escalation path.
• Data catalogueA data catalogue is a searchable inventory of an organisation's data assets with their metadata: descriptions, owners, location, quality scores and lineage. Users search it to find trusted data before building a report or model. Also spelled data catalog.
