Surrogate keys are keys that have no business meaning and are solely used to identify a record in the table. Such keys are either database generated (example: Identity in SQL Server, Sequence in Oracle, Sequence/Identity in DB2 UDB etc) or system generated values (like generated via a table in the schema).
