In the context of databases, a primary key is a unique identifier for a record in a table, ensuring that no two rows can have the same key value. A super key, on the other hand, is a set of one or more attributes that can uniquely identify a record, but may include additional attributes that aren't necessary for uniqueness. Every primary key is a super key, but not all super keys are primary keys, as they may contain extraneous information beyond what is needed for unique identification. In Linux, these concepts relate to handling data in databases rather than the operating system itself.

What are the differences between super key primary key candidate key and foreign key?
Super key: A set of attributes that uniquely identifies a tuple in a table. Primary key: A specific super key chosen to uniquely identify each tuple in a table and must be unique and not null. Candidate key: Any super key that could be chosen as the primary key. Foreign key: A field in a table that is a primary key in another table, used to establish a relationship between the two tables.

What is a super key in DBMS?
A super key in a Database Management System (DBMS) is a set of one or more attributes that can uniquely identify a record in a table. It may include additional attributes beyond what is necessary for uniqueness, meaning it can be a broader category than a candidate key. While every candidate key is a super key, not all super keys are candidate keys. The primary purpose of a super key is to ensure that no two rows in a table have the same value for the attributes that make up the super key.

Difference between primary key candidate key and super key?
A primary Key which uniquely identifies a row of table,primary key does not allow null values and also not allow duplicate values. Superkey is defined in the relational model of database organization as a set of attributes of a relation variable (relvar) for which it holds that in all relations assigned to that variable there are no two distinct tuples (rows) that have the same values for the attributes in this set. Equivalently a superkey can also be defined as a set of attributes of a relvar upon which all attributes of the relvar are functionally dependent.
