What is Transaction Isolation Levels?
Transaction isolation levels in SQL define the degree to which the operations in one transaction are visible to other concurrent transactions. There are typically four standard levels: Read Uncommitted, Read Committed, Repeatable Read, and Serializable. Each level provides different trade-offs between data consistency and concurrency. Understanding and correctly setting isolation levels is crucial for maintaining data integrity and optimizing performance in multi-user database environments.
