Oh, if all informations can be extracted from the DB there is no need to use
the TCA. I just thought some additional informations would be required. If
not it's even more easy.

That is a difficult point. It requieres some care to keep the DB model
intact, the timestamps, the user ids etc. Good documentation is of help
here. It's outside the coding standards and only good research and
documentation can show, that is equivalent. But I think it's worth the
investigation.

Developers should avoid "non-atomar" database fields. It's possible to work
with TYPO3 in a clean way, at least when setting up new tables. It's
possible, it should be the standard.

Yes that would be very nice. It seems the bigger part is already done.
