Meaning of "candidate key"
In the context of database management, a candidate key refers to a unique attribute or combination of attributes that can be used to uniquely identify each record within a table. It is a potential primary key option before choosing the actual primary key. A candidate key must have the properties of uniqueness and minimality to be considered as a primary key
