Availability, Consistency, Isolation, Decisiveness
All, Consistency, Inclusion, Dependency
2. Which property of ACID ensures that a transaction is treated as a single, indivisible unit of work?
3. Which property of ACID ensures that a transaction brings the database from one consistent state to another?
4. Which property of ACID ensures that concurrent transactions do not interfere with each other and appear to be executed serially?
5. Which property of ACID ensures that once a transaction is committed, its changes are permanent, even in the event of a system failure?
6. Which level of isolation ensures that a transaction can read uncommitted data from other transactions?
7. In the context of database transactions, what does "commit" refer to?
8. Which isolation level ensures that a transaction can read only committed data and prevents dirty reads?
9. What is the primary purpose of the "ROLLBACK" statement in database transactions?
10. Which isolation level provides the highest level of data consistency but may lead to more contention and potential performance issues?
11. What is a "dirty read" in the context of database transactions?
12. Which property of ACID ensures that transactions are executed in a specific order, as they are received by the database?
13. In the context of database transactions, what is a "deadlock"?
14. Which SQL statement is used to explicitly start a transaction in many relational databases?
15. What is the primary purpose of the "COMMIT" statement in database transactions?
16. Which isolation level allows for repeatable reads but still prevents dirty reads and non-repeatable reads?
17. In the context of database transactions, what is a "non-repeatable read"?
18. Which property of ACID ensures that once a transaction is committed, it is not lost even in the event of a system crash?
19. What is the primary purpose of the "SAVEPOINT" statement in database transactions?
20. Which property of ACID ensures that a transaction, once committed, cannot be undone or rolled back?
21. In the context of database transactions, what is a "phantom read"?
22. Which isolation level allows for the highest degree of isolation, preventing dirty reads, non-repeatable reads, and phantom reads?
23. What is the primary purpose of the "ROLLBACK TO SAVEPOINT" statement in database transactions?
24. Which property of ACID ensures that a transaction is either fully completed or fully rolled back in case of failure?
25. Which SQL statement is used to explicitly roll back a transaction in many relational databases?
