What is atomicity in database transactions?
Atomicity is a property of database transactions that ensures they are all-or-nothing. This means that a transaction will either complete fully or not at all, preventing partial updates.
Can you give me an example of atomicity in action?
Sure! Imagine a bank transfer: if you transfer money from Account A to Account B, both the debit from A and the credit to B must happen together. If one fails, the entire transaction fails.
What happens if a transaction fails?
If a transaction fails, the database will roll back to its previous state, ensuring no changes are made. This maintains data integrity.
Are there any real-world applications of atomicity?
Yes, atomicity is crucial in banking systems, e-commerce transactions, and any application where data consistency is vital.
