Isolation Levels Supported by DB2

DB2 supports the following isolation levels:

1. Read Uncommitted: This isolation level allows dirty reads, meaning a transaction can see uncommitted changes by other transactions.
2. Read Committed: In this isolation level, a transaction can only see committed data changes by other transactions.
3. Repeatable Read: A transaction will see the same data in subsequent reads within the same transaction, even if other transactions commit changes to the data.
4. Serializable: This isolation level provides the highest level of data consistency by ensuring that transactions are completely isolated from each other.

Understanding the different isolation levels supported by DB2 is crucial for ensuring data consistency and integrity in database transactions.
