I was only talking about entity EJB, and just saying they seem too close to
relationnal model to be really independant. I didn't say they prevent it.
Entity EJB are kind of white or black solution. CMP is perfect for one
object=one record model, and maybe even for 1/n or n/m relationships with
non-standards extension (i didn't tried any). But for really complex model, as
trees, graphs, and so on, you have to switch to BMP, and in this case the gain
over basic Corba solution is getting thiner IMHO.
What the difference between domain object and business object ? I found nothing
on this topic on cetus links. And is there any online ressources with practical
examples of such a design ?
Cheers
