  • Re: subset constraint validation errors

    Hello Berhanu, A subset constraint (along with an equality constraint and an exclusion constraint) is classified as a&nbsp;set comparison constraint. This means that these constraints compare the population of ordered&nbsp;sets&nbsp;of roles, not individual roles. (The instructions and error messages in NORMA refer to these sets role ...

  • Re: Objectification in the latest NORMA update

    Hi Gordon, Good to hear from you.&nbsp; A couple of comments: (minor) You can change the name of the objectifying entity type on the shape as well. Just click the name shape above the fact type. There are other uses for this shape as well. For example, if you want to use the fact editor to create a fact type with the objectifying entity type as ...

  • Re: Implicit disjunctive mandatory constraint

    Hi Matt, I don&#39;t have the book with me, so I&#39;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&#39;t even know the diagramming layer exists, including UI-only concepts such as &#39;ExpandRefMode&#39;. The only shapes that routinely don&#39;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&#39;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&nbsp;http://ormsolutions.com/tools/orm.aspx&nbsp;(one diagram at a time) or&nbsp;http://ormsolutions.com/tools/ormPrint.aspx&nbsp;(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&#39;re looking for that will install NORMA is the Visual Studio 2013 Community Edition. -Matt&nbsp;

  • Re: Model semi derived fact type in NORMA

    Hi Jacob, Once you enter your derivation note you&#39;ll see a &#39;DerivationStorage&#39; property. This defaults to &#39;Derived&#39;, but can also be set to &#39;Asserted or Derived&#39;. 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,&nbsp;http://ormsolutions.com/NORMAPreview&nbsp;is kept up to date with builds from the latest sources and will be very close to the next official build. -Matt&nbsp;
  • Re: Subset constraint terminology

    Hi Matt, I think the adjective &#39;simple&#39; always needs to be taken in the context of the thing it is describing. In math terms, a &#39;simple multiplication problem&#39; and a &#39;simple multi-variable definite integration problem&#39; set significantly different bars for the meaning of simple. I think you can take Terry&#39;s use of ...

  • Re: Subset constraint terminology

    Hi Matt, I don&#39;t think it is understood that an unprefixed &#39;subset constraint&#39; means one role per tuple. I&#39;ve used the terms &#39;single-column&#39;, &#39;basic&#39;, &#39;simple&#39;, etc. Although the NORMA UI presents rows and columns, technically each row (tuple) is an argument to the comparison operation, the argument length ...
