Consider the following schema, where the keys are underlined:
``` Employee(SSN, Name,Dept) Project(SSN,PID,Name,Budget) ``` The SSN attribute in Project is the Id of the employee working on the project, and PID is the Id of the project. There can be several employees per project, but the functional dependency PID ? Name,Budget holds (so the relation is not normalized). Consider the query ``` SELECT P.Budget, P.Name, E.Name FROM Employee E, Project P WHERE E.SSN = P.SSN AND P.Budget > 99 AND E.Name = ’John’ ORDER BY P.Budget ``` Assume the following statistical information: 1. 10,000 tuples in Employee relation 2. 20,000 tuples in Project relation 3. 40 tuples per page in each relation 4. 10-page bu?er 5. 1000 di?erent values for E.Name 6. The domain of Budget consists of integers in the range of 1 to 100 7. Indices – Employee relation On Name: Unclustered, hash On SSN: Clustered, 3-level B+ tree – Project relation On SSN: Unclustered, hash On Budget: Clustered, 2-level B+ tree a.
