Consider the following schema, where the keys are underlined (di?erent keys are underlined di?erently):

Professor(Id, Name, Department)
Course(CrsCode, Department, CrsName)
Teaching(ProfId, CrsCode, Semester)
Consider the following query:
SELECT       C.CrsName, P.Name
FROM        Professor P, Teaching T, Course C
WHERE      T.Semester=’F1995’ AND P.Department=’CS’
                  AND P.Id = T.ProfId AND T.CrsCode=C.CrsCode
Assume the following statistical information: 1. 1000 tuples with 10 tuples per page in Professor relation 2. 20,000 tuples with 10 tuples per page in Teaching relation 3. 2000 tuples, 5 tuples per page, in Course 4. 5-page bu?er 5. 50 di?erent values for Department 6. 200 di?erent values for Semester 7. Indices Professor relation On Department: Clustered, 2-level B+ tree On Id: Unclustered, hash Course relation On CrsCode: Sorted (no index) On CrsName: Hash, unclustered Teaching relation On ProfId: Clustered, 2-level B+-tree On Semester, CrsCode: Unclustered, 2-level B+ tree a.
