The BASE acronym is used to describe the properties of certain databases, usually NoSQL databases. It’s often referred to as the opposite of ACID. The BASE acronym was defined by Eric Brewer, who is also known for formulating the CAP theorem.
The CAP theorem states that a distributed computer system cannot guarantee all of the following three properties at the same time:
- Consistency
- Availability
- Partition tolerance
A BASE system gives up on consistency.
- Basically available indicates that the system does guarantee availability, in terms of the CAP theorem.
- Soft state indicates that the state of the system may change over time, even without input. This is because of the eventual consistency model.
- Eventual consistency indicates that the system will become consistent over time, given that the system doesn’t receive input during that time.
