Consider the table Authors with attributes Name, Publ, Title,andYearPub. Assume that Name is the primary key (authors’ names are unique) and hence one would expect that the DBMS would automatically create a clustered index on that attribute. Consider the statement
``` SELECT A.Publ, COUNT(*) FROM Authors A WHERE ...range pred icate on YearPub... GROUP BY A.Publ ``` a. Assume that the statement is generally executed with a very narrow range speci?ed in the WHERE clause (the publication year of only a few books will fall within the range). What indices would you create for the table and what query plan would you hope the query optimizer would use (include any changes you might make to the index on Name). b. Repeat (a) assuming that a very broad range is generally speci?ed.
