    Join

    Explanation:

    Five basic set operators in relational algebra are as follows:

    Selection - tuple selection Projection - extract columns Cartesian product - cross product of relations Set union - union of two relations Set difference - minus operation on two relations

    As we can see, Join is not part of the basic set operations but it is implemented using the Cartesian Product operator.
