ACID and Atomicity
Isolation is one of the ACID ( Atomicity, Consistency, Isolation, Durability ) properties.
Atomicity does not behave completely orthogonally with regard to the other ACID properties of the transactions.

A transaction is a series of operations performed on a database that must be done together — this is known as atomicity and is a part of ACID ( Atomicity, Consistency, Isolation, and Durability ), concepts considered to be the key transaction processing features of a database management system.
ACID and Consistency
This is not the same thing as referential integrity in databases, although it can be viewed as a special case of Consistency as understood in the classic ACID model of transaction processing.

ACID and properties
In computer science, ACID ( atomicity, consistency, isolation, durability ) is a set of properties that guarantee that database transactions are processed reliably.
The following examples are used to further explain the ACID properties.
Database practitioners often refer to these properties of database transactions using the acronym ACID.
A distributed transaction enforces the ACID properties over multiple systems or data stores, and might include systems such as databases, file systems, messaging systems, and other applications.
In the field of databases in computer science, a transaction log ( also transaction journal, database log, binary log or audit trail ) is a history of actions executed by a database management system to guarantee ACID properties over crashes or hardware failures.
