What is the role of the D (Durability) property in the ACID transaction model?

The D (Durability) property in the ACID model guarantees that after a transaction successfully completes, its changes will be saved in the database and will not be lost even in case of failures, such as power outages or system crashes.

This is achieved through mechanisms like transaction log recording, persistent data storage, and recovery procedures. Thanks to Durability, once a transaction is committed, its results become permanent and available for subsequent operations, ensuring data reliability.
