What are the benefits of using database transactions?

Database transactions ensure data integrity, consistency, and reliability during operations. They allow multiple operations to be executed as a single unit, which can be committed or rolled back together.

Can you explain how transactions help with data integrity?

Sure! Transactions help maintain data integrity by ensuring that all operations within a transaction are completed successfully. If any operation fails, the entire transaction can be rolled back, preventing partial updates that could lead to data inconsistencies.

What happens if a transaction is not used?

Without transactions, individual operations may succeed or fail independently, leading to potential data corruption or inconsistencies. For example, if a payment is processed but the inventory is not updated, it can result in overselling.

Are there any performance drawbacks to using transactions?

Yes, while transactions provide safety, they can introduce overhead. Locking mechanisms may slow down performance, especially in high-concurrency environments. However, the benefits often outweigh the drawbacks when data integrity is critical.
