ROWID
An Oracle row address value that identifies the physical location of a row within a database object and can provide direct row access while the row remains at that location.
Boundaries
ROWID is a physical row locator, not a durable business identifier. Row movement or object reorganization can invalidate assumptions about long-term identity.
