Related concepts

• Master dataMaster data is the core, shared data about the key entities a business deals with: clients, counterparties, products, accounts, legal entities and employees. It changes less often than transactions and is reused by many processes. Master data management (MDM) keeps one trusted version of it.
• Reference dataReference data is the slowly changing data used to classify or describe other data: country and currency codes, industry classifications, calendars, instrument identifiers and legal entity identifiers. Errors in it spread across every system that uses it.
• Data lineageData lineage is the documented path a data item follows from its original source through every system, transformation and control until it reaches a report, model or decision. It shows where a number came from and what was done to it. End-to-end lineage is a core expectation of the ECB for risk data.
• 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.
