What is the role of ACID in transactions?

Can you explain what ACID means in the context of database transactions?

ACID stands for Atomicity, Consistency, Isolation, and Durability. These properties ensure reliable processing of database transactions.

Why is Atomicity important in transactions?

Atomicity ensures that a transaction is all-or-nothing. If any part of the transaction fails, the entire transaction is rolled back, maintaining data integrity.

What does Consistency guarantee in a database?

Consistency ensures that a transaction brings the database from one valid state to another, adhering to all predefined rules and constraints.

How does Isolation affect concurrent transactions?

Isolation ensures that transactions are executed independently, preventing them from interfering with each other, which is crucial for data accuracy.

Can you give an example of Durability in action?

Sure! Durability guarantees that once a transaction is committed, it will remain so, even in the event of a system failure, thanks to mechanisms like logging.
