ACID
- Atomicity: Each transaction will be all or nothing. If one part fails, no changes are persisted on the database.
- Consistency: Changes to the data through transactions need to guarantee its consistency.
- Isolation: The result of concurrent execution of transactions results in a system state that would be obtained if the transactions were executed serially.
- Durability: Once the transaction is committed, the data persists.
