Study Notes

Data Persistence

Durability is a key property of a transaction in a database.
It means that the changes made by a transaction are permanently stored in the database, even if there are system failures.
In contrast to atomicity, consistency and isolation, durability handles the permanent preservation of data.
Atomicity, consistency , and isolation are all important aspects of transaction management in a database. However durability is critical for ensuring that data changes persist.
If a database system doesn't maintain durability, it is possible that data may be lost if there is a system failure after a transaction has been committed.
Durability ensures that committed transactions are safely stored and cannot be lost due to issues like system failures, power outages, or crashes.
