The concept of isolation levels in DB2 determines the ________ of transactions from each other.

Isolation levels in DB2 define the degree to which transactions are isolated from each other regarding their visibility of data modifications. It determines the extent to which transactions can see changes made by other transactions before they are committed. Different isolation levels provide varying levels of data consistency and concurrency control. Higher isolation levels offer stronger guarantees of data consistency but may impact system concurrency, while lower isolation levels prioritize concurrency but may lead to phenomena like dirty reads or non-repeatable reads. Choosing an appropriate isolation level depends on balancing data consistency requirements with performance considerations in a specific application context.
