How do I implement ACID properties in SQL?

To implement ACID properties in SQL, you need to ensure your database transactions are Atomic, Consistent, Isolated, and Durable.

Can you explain each of those properties in detail?

Sure! Atomicity ensures that all operations in 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.

What are some examples of SQL commands that support these properties?

You can use commands like BEGIN TRANSACTION, COMMIT, and ROLLBACK to manage transactions, ensuring ACID compliance.

Are there specific SQL databases that handle ACID better than others?

Yes, databases like PostgreSQL and Oracle are known for their strong ACID compliance, while others may have varying levels of support.
