Consider the join of a relation R with relation S. If R has m tuples and S has n tuples, then the maximum size of join is
| mn | |
| m+n | |
| (m+n)/2 | |
| 2(m+n) |
Question 747 Explanation:
For maximum:
If there is common attribute in R and S, and every row of R match with every row of S then total no. of tuples will be mn.
If there is common attribute in R and S, and every row of R match with every row of S then total no. of tuples will be mn.
