Hi
For my
STRUTS PROJECT....I have to connect to a database using DAOs.
I used two layerse called DAO (data access objects) and "service" layer where business logic is reside.i used DTO (datatarnsfer objects) for transfer data from frountend to backend.
later i add another layer between frount and service layer called delegate layer to redue coupling.
Actions-->delegate--> service-->DAO
my problom is what kind of methods i have to use in these layerse.
do i have to use more specific methods at delegate layer, and fewer and 'more general' ones at the DAO or othr way round?
