Abby,
We do not automatically roll-down the attributes into tables. If you want to
get the abstract class transformed to the data model, it has to be
persistent.
On the other side, to have the object model designed correctly, you should
have the attributes protected or public, as the private attributes are not
seen and can not be used by subclasses.
I am sending you an example model in a separate email.

Subject: (ROSE) Abstract Class-persistent attributes mapping into the
data model
We are currently using Rational Rose 2000e. We have to transform our
object model into a logical data model using the Rose data modeler add-in.
The model has an abstract class with 2 'private' attributes - OID and
lastUpdateTs (friendship required feature unspecified) . It is the intent of
the object modelers to have these 2 attributes flow down to all the derived
classes and then on to the logical data model.
My areas of concern:
1. Is is correct to model these attributes as private rather than protected
or public in an abstract or base class?
2. Even when I tweak the class and make the attributes 'protected' with
friendship required or even 'public' these are not carried over to the data
model when I try to transform the object to data model transformation
Any input would be greatly appreciated.
Thanks,
Abby Thakur
