Student(Id: INTEGER, Name:STRING, Address:STRING, Status:STRING)
Transcript(StudId:INTEGER, CrsCode:STRING, Semester:STRING, Grade:STRING)

(a) The following query

SELECT S.Name
FROM Student S
WHERE 3 >
SELECT COUNT (*)
FROM Transcript T
WHERE S.Id = T.StudId AND
T.Grade = 'A' AND T.Semester = 'S2002'

returns the names of all students who got an A in a more than three course in the Spring semester, 2002. Assuming that the inner and outer queries are optimized separately, what index would you choose for the inner query? What query plan would it be reasonable to expect the DBMS to use? (b) Convert the query to a non-nested form. (c) Suggest an index for the new query and a possible query plan.
