Yes; this confused me too - are there now: DAO - used to read data from DB DTO - to transfer data to app BO - to store/manipulate data for a particular "thing"
and how do any/all these interrelate with each and the Forms framework... If someone can post a reasonably clear explanation of all this, with links to examples/references, I think its worth adding at least to Wiki, if not the main docs.
