Durability in databases is the property that ensures transactions are saved permanently and do not accidentally disappear or get erased, even during a database crash. This is usually achieved by saving all transactions to a non-volatile storage medium.
Durability is part of the ACID acronym, which stands for atomicity, consistency, isolation and durability. ACID is a set of properties guaranteeing the reliability of all database transactions.
