What does ACID stand for in database transactions?
Which property ensures that either all operations of a transaction succeed or none of them are applied?
Which isolation level allows dirty reads?
A 'phantom read' occurs when:
Which isolation level is the strictest and prevents all concurrency anomalies?
A deadlock occurs when:
Which lock allows reading but prevents writing?
Which technique uses timestamps instead of locks for concurrency control?
In 2-Phase Locking (2PL), the two phases are:
Which command makes transaction changes permanent?
