Atomicity is a key aspect of database transactions, ensuring that a transaction is treated as a single, indivisible unit. If any part of the transaction fails, the entire transaction is rolled back, leaving the database in its original state. This prevents incomplete transactions from corrupting data. For example, during a fund transfer between two accounts, if the debit operation succeeds but the credit operation fails, the transaction is rolled back, and no changes are made to either account. This guarantees reliability and prevents partial updates, which could lead to data inconsistency. Why Other Options Are Incorrect :
