  • RE: multplicity constraints

    Hi Christina, If by arbitrary multiplicity constraint, you mean a constraint that limits how many times an object can play a role (as in Employee(ID) claims PersonalDay(Date) - and you want a limit to keep employees from claiming more than five personal days), you'll use a Frequency Constraint. First, create the FactType as you would ...

  • June 2007 CTP

    Hi, First thing I noticed after downloading the June 2007 CTP is that there are several installation files. There are 3 .msi files and a setup.exe file. (BTW there were no prior instances of NORMA, PLIX, or DSL tools on the machine used). I tried the setup.exe file first - why not? This installed the DSLTools, but ended the NORMA install ...

  • June 2007 CTP

    Hi, Thanks to the NORMA team for another release of the NORMA tool CTP. I did DL the folder and installed it. I'll post a few notes on that in the technical forum. The notes included with the release mentioned that this is an intermediate release, and a lot of what they have been working on is not available to the end user in this drop. ...
  • RE: Object role values with external ref sche

    Hi, The first thing that comes to mind is a disjunctive mandatory role constraint, with value constraints placed on the role in each FactType involved. So, you could have a FactType something like: (if you want all phones to be limited to this combination) Phone has Number (value set constraint) Phone has Type (value set ...
  • RE: Object role values with external ref sche

    Hi, thanks for the quick answer. In the example of the phone what I want to restrict are the allowed values for the phone number and type. I do not want to limit just the type of phones or the corresponding number but the combination of them in the values for a role played by phone. thank you, xristina

  • RE: Object role values with external ref sche

    Hi xristina, This looks like another problem where it would be much easier to analyze if we could look at the model, or model fragment you are working with. Absent that, using the same verbalization for FactTypes that the tool generates can help. Still, we can look at each of the statement/phrases in your post, and see if my interpretation ...
  • Object role values with external ref scheme

    Hi, I have an object type with an external reference scheme composed of two values (the object type participates in two associations, I have added an external uniqueness constraint on these associations, and I have etxtended the reference scheme for my object type). I would like to add the object type in an association indicating the role ...

  • RE: Assemble ORM model from multiple pages

    Oops, you're right, I forgot to provide an answer to the printing part of the question. Unfortunately, the answer (currently) is that we only support printing the current page. We pick up the printing support more or less for free from DSL Tools, whereas the multi-page models is all our own code. Because of this, the printing support doesn't ...

  • RE: Assemble ORM model from multiple pages

    Hi, I see K.O. has given you the answer to your question. I just wanted to add some comments about multi-page vs single-page ORM diagrams. In general, I think ORM diagram that are intelligently segregated into important sub-model pages are far more useful than a highly populated single graphic representation. Perhaps, as advanced ...
