Thanks for the reference. I checked out Wirfs-Brock et al at http://mogwai.simplenet.com/mood/DOOS.htm

I do not see how DOOS differs from the conceptual modelling stage of database design. Everything there certainly applies to relational domain design.

I do not see how the conceptual analysis transforms into a "clean" logical design, and I am still unclear on the meaning of "clean". Received on Wed Jun 06 2001 - 00:23:10 CDT
