- Life cycle: definition → capture → storage → usage → sharing → archival → destruction
- Quality dimensions: completeness, accuracy, consistency, timeliness, validity, uniqueness

- MDM = single authoritative record for customers/vendors/products
- ETL transforms before loading; ELT loads then transforms — validation is the control point
