What are the advantages of snapshot isolation in databases?

Snapshot isolation helps prevent phenomena like dirty reads, non-repeatable reads, and phantom reads, ensuring data consistency.

Can you explain how it differs from other isolation levels?

Unlike read committed or serializable isolation, snapshot isolation allows concurrent transactions to read a consistent snapshot of the database.

Are there any downsides to using snapshot isolation?

Yes, it can lead to increased storage requirements for versioning and may cause conflicts if not managed properly.

In what scenarios is snapshot isolation most beneficial?

It's particularly beneficial in high-concurrency environments where read consistency is crucial, like online transaction processing.
