Q1. Consider a relation s(A,B) with the following characteristics: • s has 700,000 tuples with 70 tuples per disk block • s has an index on attribute A with index height x=2 • The values that the attribute A takes in relation s are integers which are uniformly distributed in the range 1 ... 200. [Uniformly distributed ➔ there are roughly 3500 tuples for each A value.] (1.a) Assuming that the index on A is a secondary index, estimate the number of disk block accesses needed to compute the query σA=18(s). (1.b) What would be the estimated cost if the index were a clustering index?
