Updated On: Jun 16, 2025
- combination of Union and Cartesian Product
- combination of Selection and Cartesian Product
- combination of Projection and Cartesian Product
- combination of Projection and Union
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
A natural join in relational algebra can be viewed as a combination of a projection and a Cartesian product. It combines rows from two relations by matching the values of common attributes and then applying a projection to remove duplicate columns.
