Enter NoSQL
NoSQL is a blanket term for the databases that solve the scalability issues which are com-
mon among relational databases. This term, in its modern meaning, was first coined by Eric
Evans. It should not be confused with the database named NoSQL (

)
. NoSQL solutions provide scalability and
high availability, but may not guarantee ACID: atomicity, consistency, isolation, and durab-
ility in transactions. Many of the NoSQL solutions, including Cassandra, sit on the other
extreme of ACID, named BASE, which stands for basically available, soft-state, eventual
consistency.
