Durability (databases)

Durability

One of the ACID properties of transactions. It says if a transaction has committed, then it should be permanently persisted on disk, even if a crash occurs

Techniques for Crash Recovery are usually Database Transaction Logs:

• Undo Logging
• Redo Logging
• Undo/Redo Logging

In Distributed Databases for distributed transactions there are also some protocols for ensuring durability:

• Two-Phase Commit
