what are surrogate keys?

Answer Posted / deepthi pathuri

A surrogate key in a data warehouse is more than just a
substitute for a natural key.

(OR)

A surrogate key is frequently a sequential number (e.g. a
Sybase "identity column") but doesn't have to be. Having
the key independent of all other columns insulates the
database relationships from changes in data values or
database design and guarantees uniqueness.
