Solution
Q6 Part A
cost=M+N*[M/B-2]
M=550
N=300
cost=550+300*[550/(52-2)]
=550+300*[550/50]
=550+300*11
=550+3300
=3850 I/Os
Q6 Part B
cost=300+550*[300/(52-2)]
=300+550*(300/50)
=300+550*6
=300+300
=3600 I/Os
Q6 Part C
cost=3(M+N)
=3(550+300)
=3(850)
=2550 I/Os

Question 1 (5 marks) Consider two relations called Item and Orderltem. Imagine that relation Item has 160,000 tuples and Orderltem has 200,000 tuples. Both relations store 100 tuples per a page. Consider the following SQL statement SELECT * FROM Item INNER JOIN OrderItem ON Item.ItemID-OrderItem. ItemID; We wish to evaluate an equijoin between Orderltem and Item, with an equality condition Item.ltemID Orderltem.ItemID. There are 802 buffer pages available in memory for this operation. Both relations are stored as (unsorted) heap...

Consider the following relations:- Employees (eno, ename, age, phone)- Works (eno, dno, hours)- Departments (dno, dname, location)Assume that Employees relation consists of 300 pages with 100 tuples per page, Works relation contains 900 pages with 100 tuples per page, and Departments relation contains 300 pages with 100 tuples per page. Assume equal-size fields in each relation and uniform distribution of employees for departments in Works relation.Consider the following query:Select e.eno, e.ename, w.hours From Employees e, Works w Where e.eno =...
