Reserves: 5:2/05/2 Each tuple is 40 bytes long, 100 tuples per page, 1000 pages. Let's say there are 100 boats. Sailors: Each tuple is 50 bytes long, 80 tuples per page, 500 pages. Let's say there are 10 different ratings. No Indexes are available for both relations. Compare the cost of two different query plans for the following query:

Question
Consider two relations Reserves and Sailors and statistical data are as follows: Reserves: - Each In tuple 1050 Res tuple is 40 bytes long, 100 tuples per page, 1000 pages. - Let's say there are 100 boats. • Sailors: - Each tuple is 50 bytes long, 80 tuples per page, 500 pages. - Let's say there are 10 different ratings. No Indexes are available for both relations. Compare the cost of two different query plans for the following query: SELECT S.sname FROM Reserves R, Sailors S WHERE R.sid=S.sid AND R.bid=100 AND S.rating>5
