Prоblem Stаtement: In а dаtabase system, a Transactiоn is a sequence оf operations that is treated as a single logical unit. To ensure data integrity, transactions must adhere to the ACID properties. Consider the following scenario: Scenario: Alice is transferring $500 to Bob. Step 1: The bank database deducts $500 from Alice’s account. Step 2: Suddenly, the power goes out before the database can add the $500 to Bob’s account. Step 3: When the power returns, the database automatically cancels the deduction from Alice's account, ensuring money didn't just "disappear." Answer the following: Define the Acronym: Write down what each letter in C.I.D. stands for. (4 Marks) Identify the Property: Which specific property of ACID is responsible for the "All or Nothing" behavior described in the scenario above (where the half-finished transaction was cancelled)? (3 Marks) Durability Check: Once the transaction is successfully completed and "Committed," which ACID property guarantees that the data will remain saved even if the system crashes 5 seconds later?
