iScala Database Structure

Разбирался с созданием веб-приложений на основе Google App Engine. В качестве примера сделал простую страничку, показывающую структуру базы данных Scala. Получилось достаточно забавно, так что я решил все это выложить. Расположено приложение по адресу http://db.apicosoft.ru/ .
Была еще идея добавить возможность оставлять комментарии во всех разделах(объяснение для чего нужен объект, примеры кода запросов...), но сразу решил не делать, посмотрим нужно ли вообще это. Тем более, что есть куча людей, считающих такого рода информацию чуть ли не секретной - злобный пользователь прознает и залезет куда не надо.
UPDATE 24.12.2009: Оказалось, что я не совсем правильно скачал структуру (считал, что актуальная информация в ScalaSystem.mdb, а нужно было брать из ScaConvertDB.mdb). Поправил. Заодно обнаружил дополнительную информацию в ScaConvertDB. Как вам, например, такой комментарий к полю SY24001:
