How does the use of triggers contribute to maintaining data integrity in DB2?
- Triggers enforce referential integrity constraints between tables.
- Triggers ensure that specific actions are automatically performed when certain database events occur.
- Triggers improve query performance by optimizing SQL statements.
- Triggers rollback transactions when data integrity violations occur.
Triggers in DB2 are powerful tools used to enforce business rules, perform data validation, and maintain data consistency. They allow users to define actions that automatically execute when specified database events occur, such as INSERT, UPDATE, or DELETE operations. This ensures that data integrity is maintained by enforcing predefined rules and actions, such as checking constraints, cascading updates, or auditing changes.
