What is different between a key and superkey?
A key is a minimal set of attributes that uniquely identifies a record in a database table, meaning no two records can have the same value for that set of attributes. A superkey, on the other hand, is any set of attributes that can uniquely identify a record, but it may contain additional attributes that are not necessary for uniqueness. In essence, all keys are superkeys, but not all superkeys are keys, as keys must be minimal.

What is a minimal superkey?
A minimal superkey, also known as a candidate key, is a type of superkey that uniquely identifies a record in a database table while having no unnecessary attributes.

Every minimal superkey is a superkey, but not all superkeys are minimal, as superkeys may contain additional attributes that are not needed for unique identification.
