What are some examples of ACID properties in database transactions?

ACID stands for Atomicity, Consistency, Isolation, and Durability. An example of Atomicity is a bank transfer where both the debit and credit must succeed or fail together.

Can you explain Consistency with an example?

Sure! Consistency ensures that a transaction brings the database from one valid state to another. For instance, if a transaction updates a user's balance, it must ensure that the total balance remains the same before and after the transaction.

What about Isolation? How does it work?

Isolation ensures that transactions are executed independently. For example, if two transactions are happening simultaneously, Isolation guarantees that they do not interfere with each other, maintaining data integrity.

And what does Durability mean?

Durability means that once a transaction is committed, it will remain so, even in the event of a system failure. For example, if a transaction is completed and the system crashes, the changes will still be saved.
