Employee (empNo, eName, salary, position)
Aircraft (aircraftNo, aName, aModel, flyingRange)
Flight (flightNo, from, to, flightDistance, departTime, arriveTime)
Certified (empNo, aircraftNo)

 

where Employee contains details of all employees (pilots and non-pilots) and empNo is the key.

AirCraft contains details of aircraft and aircraftNo is the key.
Flight contains details of the flights and flightNo is the key.
and Certified contains details of the staff who are certified to fly an aircraft, and empNo/aircraftNo form the key.

Formulate the following queries in SQL:
List the employee numbers of employees who have the highest salary.

  • List the employee numbers of employees who have the second highest salary.

  • List the employee numbers of employees who are certified for exactly three aircraft.

  • Write code that will write Oracle sequences to produce automatic customer number and invoice number values. Start the customer numbers at 1000 and the invoice numbers at 5000.

  • Modify the CUSTOMER table to included two new attributes: CUST_DOB and CUST_AGE. Customer 1000 was born on March 15, 1979, and customer 1001 was born on December 22, 1988.


Problem 2

Question 1

Consider a database with objects X and Y and assume that there are two transactions Tl and T2. Transaction T1 reads objects X and Y and then writes object X. Transaction T2 reads objects X and Y and then writes objects X and Y.

 

(a) Give an example schedule with actions of transactions T1 and T2 on objects X and Y that results in a write-read conflict.

(b) Give an example schedule with actions of transactions T1 and T2 on objects X and Y that results in a read-write conflict.

(c) Give an example schedule with actions of transactions T1 and T2 on objects X and Y that results in a write-write conflict.

Question 2

Transaction 1 is the query

SELECT S.rating, MIN (S.age)

FROM Sailors S

WHERE S.rating = 8

 

Transaction 2 is the statement

UPDATE Sailors SET rating = 8

WHERE Name = 'John Doe'

 

What 'objects' should the DBMS lock when executing these transactions and why?

Question 3

Consider the following schema:

Suppliers(sid: integer, sname: string, addTess: string)

Parts(pid: integer, pname: string, coloT: string)

Catalog(sid: integer, pid: integer, cost: real)

The Catalog relation lists the prices charged for parts by Suppliers. For each of the following transactions, state the SQL isolation level that you would use and explain why you chose it.

 

1. A transaction that adds a new part to a supplier's catalog.

2. A transaction that increases the price that a supplier charges for a part.

3. A transaction that determines the total number of items for a given supplier.

4. A transaction that shows, for each part, the supplier that supplies the part at the lowest price.
