  • Re: Implicit disjunctive mandatory constraint

    Hi Matt, I don't have the book with me, so I'll try to answer without it: First off, a primitive entity type does not need to play a non-existential (reference) role. Country(.Code) is a valid as a complete and properly formed ORM model where Country plays only the existential role attaching it to the CountryCode value type. For a ...

  • Re: Model elements that are not displayed on any diagram

    Hi Matt, The diagrams are built as views on top of the model, not the other way around. The core model doesn't even know the diagramming layer exists, including UI-only concepts such as 'ExpandRefMode'. The only shapes that routinely don't display are those collapsed in a reference model (ENTITY(.Id)). It is also possible to have ...

  • Re: Is there a version of NORMA that runs on Mac?

    NORMA is a Visual Studio extension. Visual Studio runs on Windows, so you'll need a Windows virtual machine to run it on the Mac. You can view the diagrams from a local .orm file on a Mac browser using http://ormsolutions.com/tools/orm.aspx (one diagram at a time) or http://ormsolutions.com/tools/ormPrint.aspx (all ...

  • Re: Installation of NORMA with Visual Studio 2013 Express

    Hi William, NORMA is a Visual Studio extension package, and none of the Visual Studio Express editions allow extension packages to load in Visual Studio. The free Visual Studio edition you're looking for that will install NORMA is the Visual Studio 2013 Community Edition. -Matt

  • Re: Model semi derived fact type in NORMA

    Hi Jacob, Once you enter your derivation note you'll see a 'DerivationStorage' property. This defaults to 'Derived', but can also be set to 'Asserted or Derived'. If you mix in the storage properties you get *, **, +, or ++, with two characters indicating stored, meaning that the derived portion should also be ...
  • Re: Displaying (syntactic) data type in verbalization of model

    Hi Karl, I have some minor changes to make before changing the dll version and officially releasing. In the mean time, http://ormsolutions.com/NORMAPreview is kept up to date with builds from the latest sources and will be very close to the next official build. -Matt 
  • Re: Subset constraint terminology

    Hi Matt, I think the adjective 'simple' always needs to be taken in the context of the thing it is describing. In math terms, a 'simple multiplication problem' and a 'simple multi-variable definite integration problem' set significantly different bars for the meaning of simple. I think you can take Terry's use of ...

  • Re: Subset constraint terminology

    Hi Matt, I don't think it is understood that an unprefixed 'subset constraint' means one role per tuple. I've used the terms 'single-column', 'basic', 'simple', etc. Although the NORMA UI presents rows and columns, technically each row (tuple) is an argument to the comparison operation, the argument length ...

  • Re: Importing older models

    Hi Rick, The .imo files have an undocumented binary file format. I do not have documentation on the file format, the import code from VEA, or information on how to write a VisualModeler add-in, so there is very little I can do to remedy this situation. The Orthogonal Toolbox add-in is also posted ...
  • Re: Displaying (syntactic) data type in verbalization of model

    Hi Karl, I'll just add it in, it shouldn't be hard. If it is OK, I'll just show the numbers instead of text with them. There are currently two fields (length and scale) that are basically placeholders and appear with different names in the properties window (length becomes precision for Money and Decimal types). Translating ...
