Sometimes implenting the business logic twice is the right thing to do. For instance, let's say we have a financial application, and we need to calculate account balances (let's say it's non-trivial to do this). It seems like it would be good to have the middleware calculate it, and have PG calculate it. That way, if there is a bug somewhere in the routine that does the calculation, it will be caught. It all depends on what you're doing. ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/users-lounge/docs/faq.html
