Task 2 We are looking to optimize our database performance by delaying the output of frequently used object. In the following chart, the object X is frequently accessed by many transactions, and we must repeatedly read X from the disk to memory, update the value of X in memory, and then flush the updated value of X to the disk.

Hint: think about what the redundant operations are in the above figure and consider removing them
