A column that is created solely for the purpose of serving as a primary key and is visible to users is known as an artificial key. A synthetic key is also used as a primary key, but it is not visible to the users. A weak entity is an entity that cannot be uniquely identified by its attributes alone and depends on another entity for its existence. A natural key is a primary key that is derived from the attributes of the entity.
