How do I choose the right isolation level for my database?

What are isolation levels in databases?

Isolation levels define how transaction integrity is visible to other transactions. They control the visibility of changes made by one transaction to others.

What are the different types of isolation levels?

The main isolation levels are Read Uncommitted, Read Committed, Repeatable Read, and Serializable. Each has different trade-offs.

How do I decide which isolation level to use?

Consider factors like data consistency requirements, performance needs, and the nature of your transactions. Higher isolation levels provide more consistency but can reduce performance.

Can you give examples of when to use each isolation level?

Sure! Use Read Uncommitted for reporting, Read Committed for most applications, Repeatable Read for complex transactions, and Serializable for critical data integrity.
