I had read this line about BD,SL and TO patterns in Peabody on scwcd patterns
BD Reduces coupling between presentation and business tiers (TO, SL)
See Business delegate reduces coupling between Controller and remote java services.
From what i know that presentation tier is JSPs, htmls while business tier is servlets Then how can BD reduce coupling between presentation and business tiers.
Similarily, SL reduces coupling between BD and JNDI server.
Then how can BD reduce coupling between presentation and business tiers.
And TO I don't understand how it can do this either.
What i understand is this can only be done by MVC.
