  • Re: Concept Maps

    Hey  Well I just readed the Big Brown Book and thought that if someone needs to develop or procure the IS then is it enough to have ORM conceptual model. So if I would model the user needs with ORM then is it enough or I still need to have something else..like process model. And you are correct offcourse, there is no difference between ...

    Is it possible to validate the conceptual model without the behavioral, process or functional views? According to enterprise architecture (Zacman, Togaf) it is neccessary to have complex views. V.K

  • Re: Concept Maps

    HeyI did some research about UML and I am not sure that concentrating only for data is such a good idea anymore. In order to create functional IS, modeler should also consider other aspects how is work or process organized (who is doing what with data), functionalities (how the IS should or could be used), information need for every user etc. ...

  • Re: Different roles

    A formal foundation is needed to ensures unambiguity and executability (e.g. to automate the storage, verification, transformation and simulation of models) and allow formal proofs of equivalence and implication between models. Although ORM richer, graphical constraint notation provides a more complete diagrammatic treatment of schema ...

    I went back to the initial model. Maybe if I dont use the mandatory role dot then it is possible that commander and Chief of exercise relationship is more flexible and I don't have to show that only one of the fallowing holds. Off-course the problem that Commander can not appoint himself as chief of exercise still persists. V.K

  • Re: Different roles

     Well, maybe I still did something wrong, because it is not what I really wanted to create.  For each Commander and Exercise, that Commander appoints some Officer to lead that Exercise if and only if some Officer that is that Commander leads that Exercise. Basically for me it means, that each officer must be ...

  • Re: Different roles

     So now I have only two errors with equality constraints.  Model Error: Constraint 'EqualityConstraint1' does not have enough role sequences. Model Error: Sequence '1' of constraint 'EqualityConstraint1' in model 'ORMModel1' requires a join path. The only visual difference what I can see is the position ...

    Hey I already found myself answer to the first question. But 2 and 3 are still unresolver. V.K

    Thanks Matt I tried to create model your way. Unfortunately I have three problems: 1) Under ternary you have red line connecting two ternary parts. I looked all tutorials, but could not find how to create this type on line (subset constraint I guess). 2) Between Commander-Officer you have Subtype connector. In your model it is solid. In ...
