Nice model - thanks for sharing it. It may be useful in some upcoming work I have.
There's some unconventional use of ORM in your ORM2 example, though. Drug plays the role of being an Allergy... Surely Allergy is the objectification of "Patient is allergic to Drug" where the role of the Drug is "allergen", not ...
Thanks for your question.
There are quite a number of differences. Here are three of the main points:
1: Level of knowledge required by a non-technical domain expert.
With Entity Relationship Modeling,(ERM), a non-technical domain expert has to begin by learning about what the ERM symbols and diagrams mean. For example, the use of the ...

Thanks for helping
Thanks for the feedback. I was away in Greece for a week, then catching up, or I would have replied sooner.
As for clicking thru to the Roles, I've asked a few people, and this seems to be preferred, and of course NORMA works in a similar way. I will try to set it up like that. How does this sound: for binaries or ...

So, the ...
I'd like a forum devoted to DBMS issues, for anyone who implements databases occasionally. For example, a nice discussion about materialized views. ;)
Or is there a place already for this kind of discussions?
I read the SBVR "specification" about three years ago.
At the time I came to the following conclusions:1. Most of what SBVR claims to be able to do can be done with ORM2.
2. The SBVR "specification" is ambiguous and thus I don't see what value it has.
3. It seems to be of help to those people who want to ...
Ever since exposure to business rules in a three-day course on the topic while working at a local software company I had this intuition that ORM and SBVR had some deep underlying commonalities. This thread has reinforced that feeling, and gives hope to my idea that the two approaches (one emphasizing data, the other emphasizing business rules) ...
My apologies . I pasted the graphic in the wrong format. The bird identification model was done right.
I'll fix them and reload the PDF.
