Which of the following is a binary operator in Relational Algebra?
Show Hint
Use Division when querying "for all" relationships in databases.
Updated On: May 26, 2025
- Selection
- Projection
- Division
- Rename
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Relational Algebra operators:
- Unary: Selection (σ), Projection (π), Rename (ρ)
- Binary: Union, Intersection, Difference, Cartesian Product, Division
Division is used when we need tuples related to all values in another relation.
