In databases, there is the idea of ACID - atomicity, consistency, isolation, and durability. The concepts of atomicity and isolation are very similar. Consistency (which means that transactions bring the state from a correct state to another correct state) is somewhat implied because we assume that the write operations aren't going to randomly fail in the middle of running. Durability (which means data writes are "permanent") isn't mentioned because we aren't concerned about preventing data loss due to crashes or power loss.
