Now consider that the join is a primary-key to foreign-key joinNow consider that the join is a primary-key to foreign-key join and that S is indexed on the join attribute but R is not. Describe how R and S can be joined using an index-based nested loop join algorithm. Assume that all index pages are in memory. Indicate the cost assuming each tuple of R joins with exactly one tuple in S.
