I used to work in Ingres support and one of the things was teaching
Architecture of Ingres( seminar so just theory without handson ) .Coming
from a trainer( dong tech support training on site consulting etc) people
might have seen as shallow my discussions about advanced features of VMS.
I will try to start working on this and probably note the features which
justify
the port with some comparative findings) and see if that could get more
people interested.
