The ORM Foundation

Hi Terry, Thanks for the explanation, but you are right, it does sound strange It pops the obvious question - so why do we need the mandatory dot for? Put in other words - wouldn't it make sense then to  use an "IsIndependent Dot" instead of a mandatory dot, which is practically always there (by implication)? Cheers 

 Hi, I find it hard to understand why is it nessary to note the independacy of an objectified fact type.  In the attached PNG for example, since Teaching doesnt have a mandatory dot we know its independant. so why is it important to point it out?  Thanks

I see. thanks. I was wondering if there are any ORM excersises available somewhere. What I'm most interested in would be simply UoD descriptions, from which to generate ORM diagrams, accompained by lists of elementary facts derived from them and the final ORM diagram, so that I'll be able to compare my solution with a propper one. ...

 Hello, In my UoD each Employee(.id) has Permission(premLevel). permLevel value range is {Organisation, Region, Country}, and each level contains the lower ones (e.g., with Organisation permLevel an Emp has access to empData only in her Organisation, with Region permLevel you can access empData that is accessible for Organisation permLevel ...

Sure good news about Ken's folder (though I hope i wont need it by the time its available). I may suggest to include a glossary. The only one I found (thanks to you actually) is focused on annotations, but hardly explains the proper use of them. What I'm thinking of is more of a lexical or encyclopedic type of glossary, presenting each ...

God! you guys really did thought of everything Cheers 

Hi again, I'm trying to understand the difference between these two diagrams. I understand that there's a verbalization difference:in the case of the derivation it means that the true value of one fact is derived from the other fact in the case of the subset it means that the set of completed projects is a subset of thesuperset Project ...

Dear Terry, I'm attempting to create the secondary supertype for FeemaleManager on Leb_4 (slide 18).   As far as i understand, when I first define an object type as a subtype, the supertype is automatically defined as a primary supertype (full arrow line). When I go on to define the second supertype for the same object type, it ...

Hi, on the attached diagram (copied from the 4th NORMA lab), does the frequency constraint mean that each employee can have maximum 9 employees reporting to him? thanks

Hi, I'm looking for an easy way to communicate the Diagram to clients for approval, basically as part of the requirements analysis we provide. Some of my clients don't feel that comfortable with the diagrams, and I was wondering if there's a tool that generates some kind of verbal list of UoD rules. Just as the ORM Verbalisation ...
