I was able to get a pdf coy of the "Third Manifesto" article here:
http://citeseer.nj.nec.com/darwen95third.html
but the details of tutorial D seem not to be a part of that article.
NewSQL *might* be cool if someone found reason to use it in a DBMS.

Sometimes I wonder why its so important to model data in the "rela-
tional way", to think of data in form of sets of tuples rather than
tables or lists or whatever.  I mean, though its elegant and based
on mathematical principles I would like to know why its the _right_
model to follow in designing a DBMS (or database).  The way my mind
sees it, should we not rather be interested in what works?
