A natural key (also known as business key) is a type of unique key in a database formed of attributes that exist and are used in the external world outside the database (i.e. in the business domain or domain of discourse). In the relational model of data, a natural key is a candidate key and is therefore a functional determinant for all attributes in a relation. A natural key is sometimes called domain key.
