Quizplus · Accepted Answer

A natural key is a real-world identifier that is typically already in place and accepted in a domain, such as a social security number or a product code. It is unique and not subject to change, making it a suitable candidate for use as a primary key in a database. Foreign keys are used to link separate tables in a relational database, while surrogate keys are artificially generated and have no real-world meaning.
