A trigger is a block of PL/SQL code automatically executed in response to certain events (e.g., INSERT, UPDATE, DELETE) on a table.
Example Trigger:
CREATE OR REPLACE TRIGGER EmployeeAudit
AFTER INSERT ON employees
FOR EACH ROW
BEGIN
INSERT INTO audit_log(employee_id, action, action_date)
VALUES (:NEW.id, 'INSERT', SYSDATE);
END;
