Agree to agree to disagree. Hope in the future disagree to agree to disagree
and agree to agree about agreement:-)

Good. For xplatform we do not need neither Tk nor wx. Just excellent A+ GUI.

Absolutely. What is *included* in database is not suitable for a serious
work.
I tried so-called "data mining services" of MS SQL Server. It is like a
parody
to cluster analysis and decision trees.

Absolutely, In OLAP and Data Mining _freedom_ is the must.

Just to clarify. When I speak on A+ based car I do not mean building
database in A+
(if even it's possible). I mean building an OLAP application with
_interface_ to
one (or several) dabase(s), like Oracle, DB2, whatever. They (databases)
take
care on data storage, tables, views. A+ applications add OLAP-technology to
work with this data. Why A+ (or Python, or something else external to
database)?
Because of _freedom_ of modification and adaptation to your particular
needs.

BTW, I, as a Dyalog user, would be very appreciated if you send me any
details (probably white papers, links to web sites) about this application.
Dyalog for Windows? Which database? Any third party products? Amount and
nature of data?..

That was me.

This list should be very crowded, but is not yet. So, IMHO _clutter_,
as you say, is much better than _silence_ any way:-)

Right. Right. Right. (or Agree. Agree. Agree).
