Atomicity

Atomicity refers to the property of a transaction in a database system being "atomic" or indivisible. It means that either all the operations within a transaction are successfully completed and the changes are permanently saved, or none of the operations are completed and no changes are made. In other words, a transaction is treated as a single, all-or-nothing unit of work.

Atomicity ensures that the database remains in a consistent state even if there are failures or errors during the execution of a transaction. If a failure occurs during a transaction, all the changes made by the transaction are rolled back, and the database is restored to its state before the transaction started.

This property is important in maintaining data integrity and ensuring that the database remains reliable. It allows multiple concurrent transactions to be executed in parallel without interfering with each other, as each transaction is isolated and independent of others
