No, no necessary; the default alias is the DataSource, but when there
are two aliases in play, I prefer the explicit naming.

That would be unwieldy, to say the least. It would force an additional
requery for each child bizobj whenever the parent record changed. With a join,
the lookup data is gotten in the initial query, and no subsequent queries need
to be run.

Yes, those are changes that were more recent. The point of the
tutorial, though, is to create those files yourself; the downloadable code is
simply to compare against if you get stuck, or otherwise are curious as to what
the finished code should look like.
