Anyone have any good ideas on saving changes made to certain fields to a table every time the value of the field is changed?

I want to use field level triggers in the fields I want to capture, within the tables in the DBC, to save every time the value of that field changes. I would like to save the change to another table that has same field structure as the field being changed. I don't want to save the change to a memo file, it's a pain if I need to research and I can't quickly add the value back to the original table.

Is there a discussion on this subject somewhere out on the thread?
