Hi Jaview,
I use several different classes. DE, Container, Relation, Session, etc.
Remember, if you design using a class like Container, you can always put it in it's own private datasession by using a Session object to create it.

oPS = NEWOBJECT("SessionBase", "SessionBase.PRG")
oBiz = oPS.Create("MyBizObj", "Some.PRG")

************************************
DEFINE CLASS SessionBase AS Session
   PROCEDURE Create (ClassName, ClassLib)
       RETURN NEWOBJECT(m.ClassName, m.ClassLib)
   ENDPROC
ENDDEFINE

>Hi all, I use Session class for my business objects, but I don't really know if DataEnvironment class would be a better class (or any other for that matter).
>
>I'm seeking for advice on which class is more suited for business objects, and what are the pros and cons of using one approach or the other.
