Problem 2: wn, As B (number of buffer frames) grows, one's join algorithm choice can change: Order the four relevant join älgorithms (Blocked-nested loop, index-nested loop, sort-merge, hash-based) based on increasing values for B. Hence, for small B, which would you choose? As B grows, which algorithm then becomes your choice, and what is the corresponding threshold value for B? Order all four algorithms and provide the three threshold values. Assume that the two relations R and S have sizes M and N respectively. W.l.o.g. assume M > N, and that the join attribute is a key value in S and a foreign key in R. Assume any index you might need exists, and provide any assumptions you are making.
