Detailed explanation-1: -Four crucial properties define relational database transactions: atomicity, consistency, isolation, and durability-typically referred to as ACID. Atomicity defines all the elements that make up a complete database transaction.

Detailed explanation-2: -Atomicity is a property that ensures that a database follows the all or nothing rule. In other words, the database considers all transaction operations as one whole unit or atom. Thus, when a database processes a transaction, it is either fully completed or not executed at all.

Detailed explanation-3: -Atomicity means that multiple operations can be grouped into a single logical entity, that is, other threads of control accessing the database will either see all of the changes or none of the changes.

Detailed explanation-4: -Atomicity requires that each transaction be “all or nothing": if one part of the transaction fails, then the entire transaction fails, and the database state is left unchanged. An atomic system must guarantee atomicity in each and every situation, including power failures, errors, and crashes.
