You sound like you're trying to implement something like materialized
views one at a time; have you considered adopting the more general
techniques used to maintain those so that you're not doing custom
development each time for the design?

I think that sort of approach is more practical than it would have been
for you in MySQL, so maybe this wasn't on your list of possibilities before.
