Answer:

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.
