Is it possible to get all the verbalizations from a model,
instead of just a single element, so that I can print the
list for manual validation?

Hi,
As things are now, what types of tests of the NORMA tool would be most helpful to your team? Of course you want to know about any bugs found by users, but are there specific areas where you need more testing or feed back? Also, are there areas where the you will be replacing a significant part of the tool system, and further comments ...

Hi,
I won't try to pin anyone down to a date certain, but can you pass along the time scale expected for the next CTP release? If we knew that the next release was due in days, weeks or months, that could effect the kind of testing we'd do - and the kind or comments, questions and feature requests that we are likely to submit. Any kind of ...

Hi,
Can someone tell me why ORM objects generate what looks like superfluous cancatenation for column names in the DDIL script files? Even in very simple models, without nesting, or ring constraints, I see column names in the form: Xxxxx_Xxxxx_Name, or Yyyy_Yyyy_Code, etc.... It doesn't look as though the method is used to prevent duplicate ...

> Actually, I do think that a deontic constraint should be implemented
Yes, I agree - but it cannnot be enforced mandatorily.
There's no standard ''warning'' system in SQL or semantics
defining what should happen when a warning occurs, which
is why I said: ''Should mostly be true, I'll enforce it,
make it easy for me to do it''.
The ...

Hi,
Whether a warning or fatal error is the effect you want, when a constraint is violated, depends on the target of the modeling. As I am most concerned with modeling RM compliant relational database schemas, I don't want anything to get by that would break compliance and open the DB to data integrity errors. As ORM can be used for other ...

Actually, I do think that a deontic constraint should be implemented. An alethic constraint is verbalized in terms of ''must''; e.g. a race horse must have exactly one trainer. If you break an alethic constraint an error should be issued and the operations should be denied. A deontic constraint is verbalized in terms of ''should''; e.g. a race ...

Hi,
Thanks for the reply. I was curious about how a deontic constraint was implemented. Apparently, it's not - unless you implement it in some manor outside of the scope of what the tool will generate. That's Ok, as long as clearly denoted as such. Maybe there should be a method of marking these constraints on the diagram (color from red to ...

Hi,
I had just looked at the associated .xml files and seen the warning about the 'SubsetConstraint1' having gone missing in action, and was going to point that out to you! You beat me to the punch. Though I'm not pleased that a feature as important as this one isn't implemented yet, (it would be helpful if any feature not yet implemented was ...

I haven't used deontic modality in ORM, but I have used it elsewhere (like in my data layer generator). Basically it's saying to the tool ''Don't enforce this constraint because it may occasionally or temporarily get violated - I'll enforce this one myself!''. In other words, don't generate SQL that enforces it, leave enforcement to the business ...
