ACID stands for Atomicity, Consistency, Isolation and Durability. Everything refers to a property of database transactions.
Atomicity : This refers to that the transactions are atomic which means that the result of the transaction can either be a success or a failure and nothing in between.
Consistency : This property implies that the state of the database has to remain valid after the completion of the transactions.
Isolation : This implies that the presence of multiple transactions does not hinder each other as well as the state of the database.
Durability : This states that post-commit of a transaction, the data should not be lost even if there is a power failure.
