Nested-loop join:
Use R1 outer relation we need,
  ...
Explanation of Solution
b.
Block nested-loop join:
- If R1 is outer relation, we need ceiling (800 / (M−1)) ∗ 1500 + 800 disk accesses...
Explanation of Solution
c.
Merge join:
Let R1 and R2 be unsorted relation, and M be the pages of memory.
If M>800, then it is easy to do join in 2300(800+1500) disks.
Therefore, we will only take case where M<=800 pages...
Explanation of Solution
d.
Hash join:
Let us assume that there is no overflow in the join then R1 is smaller than R2, there for e will use R2 as probe relation and R1 as build relation...
