>What is the easiest way to populate a Date of Last Update field with the current date if the value for ANY other field has changed? I am using table buffered views. I believe this eliminates the use of Update Trigger.

You can't use the update trigger anyway, as that would cause infinite recursion. That's why update triggers don't allow you to modify any table values.

The only place that you can do this at the database level that I am aware of is the Record validation rule.
