Quizplus · Accepted Answer

An artificial key, also known as a surrogate key, is a type of primary key that is added to a table specifically for the purpose of serving as the primary identifier for each record. Unlike natural keys that are derived from existing data attributes and have a logical relationship to the data, artificial keys have no business meaning and are usually created when a suitable natural key does not exist or is impractical to use. They are visible to users and are often used to ensure each record can be uniquely identified, especially in complex database structures.
