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...

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...

A population is - All the individuals of a particular species within a given area at one point in time Based on past rates of birth and death you set up a logistic model of a dolphin population. This model predicts that there will be 10,020 dolphins next spring. How should you interpret this model's prediction? - There will probably be about 10,000 dolphins next spring, but many outside factors might cause the population to increase or decrease unexpectedly. At a certain population size c...
