Serializable Isolation

Serializable isolation is a level of database transaction control that ensures transactions are executed in a way that produces the same results as if they were processed one after another, rather than concurrently. This means that even when multiple transactions occur at the same time, they will not interfere with each other, preventing issues like lost updates or inconsistent reads. It provides the highest level of data integrity and prevents anomalies, but can reduce performance because it requires more locking and coordination to maintain this strict order.
