ACID properties. Relational databases provide atomicity, consistency, isolation, and durability (ACID) properties: Atomicity requires a transaction to execute completely or not at all. The ACID properties of a database are Atomicity, Consistency, Isolation and Durability. ‌ Atomicity — An “all or nothing” approach. If any statement in the transaction fails, the entire transaction is rolled back. Consistency — The transaction must meet all protocols defined by the system. Couchbase.
