I really like you blog and I found useful information on it.
I would like to make a kind of blog reader request 😉
– Could you please write something about Supertype and Subtype Roll-up/Roll-down when transforming a logical data model into a physical data model? I think it is an interesting and has a big influence in the ETL development.
– I used to work with #PowerDesign but in my current company #ERwin is the modelling tool. Are you planning to write some ERwin or better erwin Inc. articles?
Greetings from Nuremberg,
Hello Paul, thanks for liking my blog 🙂
I’ve got some training material relating to Supertype and Subtype Roll-up/Roll-down, which I could turn into a blog entry. There is a book on PDM design and management on the cards, but that won’t arrive for quite a while.
Sorry, but I don’t plan to write any ERwin articles (though the ERwin marketplace is getting more interesting these days, so I might change my mind). I have some ER/Studio stories I can tell.
