Consider two relations R(x,y) and S(y,m) with B(R) = 1,000, B(S)

Consider two relations R(x,y) and S(y,m) with B(R) = 1,000, B(S) = 500, and M. 101. Assume that attribute y of relation R has two distinct values (y1 and y2) and the values are evenly distributed in R. Similarly, attribute y of relation S has the same two values (y1 and y2) and the values are evenly distributed in S. Suppose that initially both relations are not sorted by attribute y. Compute the total number (in average) of disk I/Os that are needed for the sort-merge join algorithm in order to compute RDA S
