Is there a Model Integrator in Rational XDE Developer?
Yes, but it’s not a separate application as in Rational Rose; rather, you access its functionality via the Compare-Merge submenu of the File menu. (Consequently, the documentation refers to it as the compare-merge capability rather than the Model Integrator.) Since this functionality is part of Rational XDE Developer itself, you can browse the results of the merged model as it’s being created.
