Sensible use of triggers may transform the way that an application is designed. The user interface can be fully designed, and then the complexities and rules can be introduced later by using table validation rules and database trigger functions. The resulting design is much more in the "object oriented" style. Triggers separate "business function" from "user interface" in a much clearer and easier way.
