Explain Transaction Isolation, and what are the various types of Transaction isolation in RDBMS ?

Question

Accepted Answer

Transaction isolation is a concept in databases that ensures transactions are executed independently of each other.

Transaction isolation levels determine the degree to which one transaction must be isolated from other transactions.
Types of transaction isolation levels include Read Uncommitted, Read Committed, Repeatable Read, and Serializable.
Each isolation level offers a different level of consistency and concurrency control.
For example, in Read Uncommitted isolation level, transactions can read uncommitted data, while in Serializable isolation level, transactions are completely isolated from each other.
