What are the ACID properties in databases and why are they important?

ACID stands for Atomicity, Consistency, Isolation, and Durability. These properties ensure reliable transactions in databases.

Can you explain each of the ACID properties in detail?

Sure! Atomicity ensures that all parts of a transaction are completed successfully or none at all. Consistency guarantees that a transaction brings the database from one valid state to another. Isolation ensures that transactions do not interfere with each other, and Durability means that once a transaction is committed, it remains so even in the event of a system failure.

Why is it crucial for databases to maintain these properties?

Maintaining ACID properties is crucial for data integrity and reliability. They prevent data corruption and ensure that transactions are processed accurately, which is vital for applications like banking and e-commerce.

What happens if a database does not follow ACID properties?

If a database does not follow ACID properties, it can lead to data inconsistencies, loss of data integrity, and unpredictable behavior, which can severely impact applications and user trust.
