Something I have been doing for a while now is making Application.dao and
Application.gateway structs to store all my data abstraction and then passing
those to beans.
Basically, I have a DAOBean object that many of my beans extend which contains
getDAO() and setDAO() functions for passing the reference.
This approach has worked really well thus far, but I want to start making a
factory for creating a new bean (or reading one) as I like that better than
using the bean.load() mechanism that the Active Record pattern typically
uses.
Sorry if this sounds like random jibberish as I haven't been sleeping enough
haha.
Later,
Mike.
