Atomicity in Databases

Atomicity is a property of database transactions that ensures all changes are treated as a single, indivisible unit of work.
It guarantees that either all changes are committed to the database or none are, maintaining data consistency.

Significance of Atomicity

Atomicity is significant in maintaining data integrity by preventing partial updates that can lead to inconsistent data.
It ensures that the database remains in a valid state, even in the event of errors or failures.
