ACID Properties: is Used for Maintaining Transaction where ACID Derive as given Below A-Atomicity:- Each transaction is said to be atomic if when one part of the transaction fails, the entire transaction fails. C-Consistency:- The consistency property ensures that the database remains in a consistent state before the start of the transaction and after the transaction is over (whether successful or not). I-Issolation:- Isolation refers to the requirement that other operations cannot access or see the data in an intermediate state during a transaction. D-Durability:- Durability refers to the guarantee that once the user has been notified of success, the transaction will persist, and not be undone.

ACID (an acronymn for Atomicity Consistency Isolation Durability) is a concept that Database Professionals generally look for when evaluating databases and application architectures. For a reliable database all this four attributes should be achieved. Atomicity is an all-or-none proposition. Consistency guarantees that a transaction never leaves your database in a half-finished state. Isolation keeps transactions separated from each other until they're finished. Durability guarantees that the database will keep track of pending changes in such a way that the server can recover from an abnormal termination.
