Which of the following is NOT a property of database

Solution

The ACID properties —Atomicity, Consistency, Isolation, and Durability—are fundamental principles that ensure reliable processing of database transactions.

• Atomicity ensures that a transaction is all-or-nothing: either all its operations are completed, or none are.
• Consistency guarantees that a database moves from one valid state to another, preserving integrity constraints.
• Isolation ensures that transactions execute independently, preventing intermediate states from affecting others.
• Durability ensures that once a transaction is committed, its changes are permanent, even in the event of system failure.

• Atomicity: Central to ACID; ensures transactions are indivisible units of work.
•  Consistency: Prevents integrity violations by ensuring valid state transitions.
•  Isolation: Key to ensuring concurrent transactions do not interfere improperly.
•  Durability: Protects committed transactions from system crashes.
