What are some examples of ACID properties in databases?

ACID stands for Atomicity, Consistency, Isolation, and Durability. For example, in a banking system, when you transfer money, the transaction must be atomic—either the money is transferred completely or not at all.

Can you explain each of the ACID properties?

Sure! Atomicity ensures that all parts of a transaction are completed successfully. Consistency ensures that a transaction brings the database from one valid state to another. Isolation ensures that transactions occur independently without interference. Durability guarantees that once a transaction is committed, it remains so, even in the event of a system failure.

What happens if a transaction violates one of these properties?

If a transaction violates any ACID property, it can lead to data corruption, inconsistencies, or loss of data integrity. For instance, if atomicity is violated, you might end up with partial updates that leave the database in an invalid state.

Can you give me a real-world example of ACID in action?

Certainly! Consider an online shopping platform. When you place an order, the system must ensure that the inventory is updated, the payment is processed, and the order confirmation is sent. All these actions must be completed successfully to maintain data integrity.
