Comparison of join algorithms. Consider two relations rl and r2 with schemas R1(ABC) and R2(CDE). Suppose we know that ri has 10,000 tuples, r2 has 15,000 tuples, 25 tuples of r fit on one block, and 20 tuples of r2 fit on one block. Assume that there are M-400 pages available in the memory. Estimate the number of block transfers and seeks required, using each of the following join strategies for ri x r2 (show your work): () Nested-loop join (i) Block-nested loop join iii) Merge join (iv) Hash Join
