The key that retains its uniqueness even after you remove some of the fields is known as a "superkey." A superkey is an attribute or a combination of attributes that can be used to uniquely identify a database record without referring to any other data. Each table row has a unique superkey. It is important to note that a superkey may consist of a single column or a combination of multiple columns.
