Hi sir I have one doubt. Consider this scenario There are two users A and B. A updates the sal from 1000 to 2000 without committing. So data buffer will contain the block with new value 2000. After that B selects the same row but he gets old value 1000. Can you explain how as far as I know system process first look the block in data buffer cache and buffer cache contains block with salary 2000
