- Surrogate vs Natural Keys
- https://en.wikipedia.org/wiki/Surrogate_key
-
https://en.wikipedia.org/wiki/Natural_key
- A natural key differs from a surrogate key which has no meaning outside the database itself and is not based on real-world observation or intended as a statement about the reality being modelled. A natural key therefore provides a certain data quality guarantee whereas a surrogate does not. It is common for elements of data to have several keys, any number of which may be natural or surrogate.
