Consider two database relations R and S having m tuples in R and n tuples in S. What is the maximum number of tuples that could appear in the natural join of R and S?
NOTE:
MIN(m, n) will return a minimum of m and n
MAX(m, n) will return a maximum of m and n
1
m × n
2
MIN(m, n)
3
MAX(m, n)
4
m + n
5
m / m
