And I'm answering for UDD.

Gather as much data as possible about Debian in a single database,
making it easy to data-mine it.

http://svn.debian.org/wsvn/collab-qa/udd/?rev=0&sc=0
It runs on udd.debian.net, a domU provided by the dalug farm. Currently,
4 or 5 persons have access to it, but it is possible to give access to
other interested persons.

The database can be accessed remotely from alioth and master.
There's also http://udd.debian.net/, but we don't have any cool web
interface yet. It's also not a goal for UDD.
Some information is also available from http://wiki.debian.org/UDD

Most of it is written in python. The Debbugs importer is written in
perl, to make use of the existing perl libraries.

single pgsql database. Schema available from
http://svn.debian.org/wsvn/collab-qa/udd/src/schema/?rev=0&sc=0

sources/packages files, bugs summary (all the info for all bugs, except
the bug logs), carnivore, lintian, list of orphaned packages, popcon,
testing migrations history, upload history.

> - Which data do you generate locally? (using tests, for example?)

we don't really generate any data locally. For some data sources, after
the "raw" import, we pre-compute some data. An example is the popcon for
sources packages.
