NHibernate is not for domain modelling, it's for DTOs. When I create domain classes, they are from-scratch and designed to look and act exactly like my domain. Persistence concerns come at least second in my overall architecture. I think questions like this are typical of folks who think "data first" instead of "domain first." Change your thinking and the answer becomes obvious regarding NHibernate. The answer is, don’t. NHibernate is not for domain modelling, it’s for DTOs.
