The base consistency model is primarily used by aggregate stores, including column family, key. Transactions access data using read and write operations. Acid (atomicity, consistency, isolation, and durability) is an acronym and mnemonic device for learning and remembering the four primary attributes ensured to any transaction by a transaction manager (which is also called a transaction monitor). It’s ok to store a data element again because nosql databases don’t join across tables.

Everything in a transaction succeeds or the entire transaction is rolled back. Overall, the base consistency model provides a less strict assurance than acid: If any statement in the transaction fails, the entire transaction is rolled back. Data will be consistent in the future, either at read time (e.g., riak) or it will always be consistent, but only for certain.
