What are the different types of transaction isolation levels?
There are four main types of transaction isolation levels: Read Uncommitted, Read Committed, Repeatable Read, and Serializable.
Can you explain what Read Uncommitted means?
Read Uncommitted allows transactions to read data that has been modified but not yet committed by other transactions.
What about Serializable? How is it different?
Serializable is the strictest isolation level, ensuring that transactions are completely isolated from one another, preventing any concurrent access.
Which isolation level is the most commonly used?
Read Committed is the most commonly used isolation level as it balances performance and data integrity.
