Question 1 (20 points) 2.1) (4 points) B - 1 buckets 2.2) (4 points) Recursively apply hash-based projection technique to further split the buckets with different hash functions until no more partition overflow. 2.3) (4 points) (B - 1)^2 buckets 2.4) (4 points) Accelerate the record matching in memory or reduce CPU cost of record matching. 2.5) (4 points) No. In the probing phase, using the same hash function will assign each data record into the same bucket. No speeding up for join in th...

Question 1 (20 points) 1.1) (6 points) Block Nested Loops Join (A) Reads = |R| + |S| * ceil(|R|/(B-2)) = 5,000 + 15,000 * ceil(5,000/(800-2)) = 110,000 (B) Writes = 0 (no writes are required for nested loops joins) 1.2) (7 points) Grace Hash Join (A) Reads in Partition phase = |R| + |S| = 20,000 Reads in Probe phase = |R| + |S| = 20,000 Total reads = 2 * (|R| + |S|) = 40,000 (B) Total writes = |R| + |S| = 20,000 1.3) (7 points) BNJ = 110,000 * 1 [reads; no writes] = 110,000 GHJ = 40...

Algorithm efficiency typically measured by the algorithm's computational complexity Computational complexity the amount of resources used by the algorithm. The most common resources considered are the runtime and memory usage. runtime complexity a function, T(N), that represents the number of constant time operations performed by the algorithm on an input of size N Space-complexity (of an algorithm) a function, S(N), that represents the number of fixed-size memory units...
