The most restrictive transaction isolation level is Serializable. This level guarantees that transactions will be executed in a fully isolated manner, with each transaction appearing to execute as if it were the only transaction in the system. This is done by placing locks on data that prevent other transactions from accessing it until the first transaction is complete. While this level provides the highest level of isolation, it can also result in deadlock situations if not implemented carefully.
