What are the implications of isolation levels?

What are the different isolation levels in databases?

The main isolation levels are Read Uncommitted, Read Committed, Repeatable Read, and Serializable. Each level balances consistency and performance differently.

What are the implications of using a lower isolation level?

Using a lower isolation level can improve performance but may lead to issues like dirty reads, non-repeatable reads, or phantom reads.

Can you explain dirty reads?

A dirty read occurs when a transaction reads data that has been modified by another transaction but not yet committed, leading to potential inconsistencies.

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

Consider the trade-offs between data consistency and performance. Analyze your application's requirements and the potential impact of anomalies.
