BASE is an acronym describing the design principles behind many NoSQL and eventually consistent databases. BASE often contrasted with ACID and its stands for:
- Basic Availability – the system guarantees availability, even if parts of it fail or are inconsistent.
- Soft state – the state of the system may change over time, even without input because of replication or background updates.
- Eventual consistency – the system will become consistent eventually, once all updates have propagated.
