Exercise 8.7 If you were about to create an index on a relation, what considerations would guide your choice? Discuss: 1. The choice of primary index. 2. Clustered versus unclustered indexes. 3. Hash versus tree indexes. 4. The use of a sorted file rather than a tree-based index. 5. Choice of search key for the index. What is a composite search key, and what considerations are made in choosing composite search keys? What are index-only plans, and what is the influence of potential index-only evaluation plans on the choice of search key for an index?
