  • Feature Request - add verbalization for ring constraints

    Hi, Verbalization of ring constraint fact types would help in model creation and validation aspects.  It would be a handy addition to the capabilities of the Verbalization browser to be able to select a fact type, and see the associated ring constraint included in the readings. Thanks, BRN..
  • Re: Generate a 'submodel' by selecting a set of diagrams

    It's important to establish a proper metamodel for this model partitioning before considering the tool support for the selected metamodel. Please consider my proposal of using multiple "vocabularies" and a vocabulary "import" operation with "correspondences" as I briefly outlined in another thread in this forum. ...

  • Re: Link several ORM models together

    Eric, I think your question is tool related... which means that the answer depends on the tool. I don't think it's possible yet in NORMA, but my ActiveFacts project has a facility for handling it. I use some SBVR terminology; a model or schema is called a vocabulary.

  • On the Universe of Discourse

      One term of acknowledged importance in Object Role Modeling is that of Universe of Discourse (UofD), also know as domain of discourse, or more simply, domain.  However, within the community of Information Systems designers, architects and practitioners (and perhaps within the subset of fact-based modelers as well), several ...

    Is there a way to link keys (foreign keys) from one model to another that are located in a separate schema?

  • What are the origins of ORM?

    The roots of logic and deductive reasoning are to be found in the writings of Aristotle (384 BC - 322 BC) in a collection known as "The Organon".  Aristotle's ideas formed the basis of logical thought until the 19th Century when writers such as De Morgan (1847), Boole (1854), Cantor (1874) and Frege (1884) introduced new ideas ...

  • Philosophy

    Hi Ken, Would it be possible to have a Forum called 'Philosophy' under 'Research'. It's just that a couple of us want to discuss the Philosophy of ORM in an open Forum, and believe this site to be a good place to do that. Best regds Victor

  • Re: Finding Euclid in ORM

    Hi Brian, I don't know where I got John from. I apologise. On Join Subset Constraint, I believe the intended interpretation, and we'll most likely find when it is implemented in NORMA, is that it operates in a manner that "If you can't query it, you may as well not be able to store it"....so my reference to ...
