Durability

See also ACID (Atomicity, Consistency, Isolation, Durability)

Durability, in the context of database management systems (DBMS), is a fundamental property ensuring that committed transactions persist even in the event of system failures or system crashes. It guarantees that once a transaction is successfully committed, its changes are permanently saved and will not be lost due to system failures or power outages. Durability is achieved through mechanisms such as write-ahead logging, transaction journaling, and data replication, which ensure that committed data is safely stored on non-volatile storage devices, such as disk drives or solid-state drives. This property is critical for maintaining data integrity and data reliability, as it ensures that users can trust the durability of their data, even in the face of unforeseen failures. Durability is one of the key components of the ACID (Atomicity, Consistency, Isolation, Durability) properties, which define the database transaction reliability and database transaction integrity.
