Question

Suppose that you are running manually the Apriori algorithm to find the
frequent itemsets in a given transaction database. Currently, you have
determined the candidate set of 2-itemsets, C2, and the corresponding
support count of each candidate 2-itemset. Assuming that the minimum
support count is 3, which candidate 2-itemsets in C₂ would be frequent 2-
itemsets? Select all that apply.
{I1, I2), support count = 1
{I₁, I3}, support count 3
{I₁, I4}, support count = 3
{I2, I3), support count
{I2, I4}, support count = 1
{I3, I4}, support count = 4
= 2

Given the following transaction dataset: Tid Items 10 A, C, D 20 B, C, D 30 A, B, C, D 40 B, D 50 A, C, D And a minimum support of 3 (minsup = 3) What are all the frequent itemsets? What are all the rules from these frequent itemsets?
Consider a relation R(a, b, c, d) containing 1 million records, where each page of the relation holds 10 records. R is organized as a heap file with unclustered indexes, and the records in R are randomly ordered. Assume that attribute a is a candidate key for R, with values lying in the range 0 to 999,999. For each of the following queries, name the approach that would most likely require the fewest I/Os for processing the query. The approaches to consider follow: ■ Scanning through the whole heap file for R. Using a B+ tree index on attribute R.a. Using a hash index on attribute R.a. The queries are: 1. Find all R tuples. 2. Find all R tuples such that a 50 and a < 100.

Consider the join r ▷◁ s of two relations r and s whose common attribute set is {A}. Physically, r is stored on 25 blocks and s on 21 blocks on the disk, tuples in both relations are unordered. Assume that the buffer pool allocated for carrying out the join has 3 frames. Compare block nested-loop join against merge join in facilitating r ▷◁ s by analyzing their I/O costs. The I/Os for exporting the final joined results to the disk is called the reporting cost, which shall be excluded from the calculation of the I/Os of r ▷◁ s, because the reporting costs of both nested-loop join and merge join cancel each other out in the comparison. Specifically, (a) Compute the # of I/Os, excluding the reporting cost, engaged by block nested-loop join. (b) Compute the # of I/Os, excluding the reporting cost, engaged by merge join in the worst-caseand best-case scenarios, respectively. Here a scenario indicates an instantiation of the tuples in rand s.
