Chapter 15, Problem 19E
Explanation of Solution
Hybrid merge join
- It is a variation on merge join operation, which is performed on unsorted tuples, when both join attributes have secondary indices.
- It is created when both the relations have a stored secondary index on the join attributes but are not physically sorted will have following modifications:
- Initially, merge the nodes of the first sorted secondary index with the node of the second sorted secondary index...
