Можно ли обеспечить ACID при уровне Read Committed?

The Read Committed isolation level guarantees that a transaction only sees committed data, preventing dirty reads. However, it does not protect against non-repeatable reads and phantom reads.

ACID includes four properties: Atomicity, Consistency, Isolation, and Durability. For complete isolation that prevents all read anomalies, the Serializable level is usually required.

Therefore, at the Read Committed level, full adherence to ACID cannot be guaranteed, especially regarding isolation, as non-repeatable and phantom reads are possible.

If strict isolation and ACID guarantees are needed, it is advisable to use the Serializable level or implement additional locking mechanisms and transaction controls.
