Yes I believe that to be true in the respect that you can access data by
defining XML constructs to get at data, rather than writing a bunch of
code to manipulate data.

Currently none as Integrator has been officially started.  That said you
could use our reports engine to do some interesting things.

The answer will be yes it will store into XML.  Whether you write it as
XML or it only deals with XML in memory likely will depend on your
transformations needs.

That is one of the requirements.

Much like our UI layout engines there are report filters.  That is an
output to XML is created and based on the type of output you want a
transformation occurs.

No.  I plan on putting budget/planning stuff in place in GNUe SB, seeing
how its what I do for a living. :)

Many OLAP engines are written in the A Programing Language (APL) created
at Morgan Stanley.  Because of its history it does this sort of thing
really well.  There is a GPL version of this coming out of Morgan Stanley
itself.  Called A+.  I have spoken with them a few times about maybe
working with GNUe to make a "Data Warehouse" extension to GNUe, but there
is minimal interest.  We have no programs willing to learn A+. ;) is the URL.

Hope this helps.
