  • Re: Missing Relational View Table?

    Ken, Good points. Let me give you a little background on this project. As a semi-retired computer/communications system engineer with a longstanding interest in education and in physics, I became interested in the work being done by the physics education research group at the University of Minnesota. One aspect of our research is the measurement ...

  • Re: Missing Relational View Table?

    Ken,  Aha - Insight! I think that I am beginning to see a glimmer of light in what you and Matt are emphasizing. Your examples are most useful; although, I need to ponder them more. Please correct me if I'm wrong, but the first thought is that when considering reference modes, I should be thinking about using ones that make sense in the ...

  • Re: Missing Relational View Table?

    Matt,   Thanks for the critique of my model. The advanced database design course I took from Gordon Everest in the spring of 2010 introduced me to ORM and NORMA. I was instantly sold on it because it filled a nagging discomfort with diving directly into an ER model. ORM provided  the ability to verbally express the ...

  • Missing Relational View Table?

    I've been using NORMA_VS2008_2012-04CTP Build 1487 to model university class meeting patterns for a physics education research database. The attached, zipped .orm and .docx files show the tables generated in the relational view. It seems that there may be a missing table that should be called Campus. The verbalization seems to imply that ...

  • Re: Decoding NORMA Relational View

    Matt,  Just getting back to this. Thanks for the information. This explained a lot. I also noticed that there are also entries in the relational view tables with no indicators (PK, FK, U) They seem to correlate with objects for which there are no uniqueness constraints on their role box. I think that I probably need to take another look at ...

  • Decoding NORMA Relational View

    When I look at the tables created in the NORMA relational view tab, I notice that some table elements are bold and some are not, and that some are prefixed by PK, FK, U# or nothing at all. Where can I find information on how to decode the meaning of all this? Thanks.  Richard

  • Fragments in Two Files

    I like using NORMA to develop ORM model fragments, including populating them with test data, and saving them in separate files. Is there a way to move the fragments into a common file - either using import/export, cut/paste or some other capability?
  • Rigid Subtypes

    In "Temporal Modeling: Part 4," Terry Halpin discusses using rigid subtypes in ORM and provides some examples (e.g., in figures 3, 4, and 7). Is there any way of identifying/portraying rigid subtypes in NORMA, even though rigidity is a dynamic constraint?

  • Re: Is Mandatory dot position

    Ahaa - Insight! Matt was right. As a matter of visual preference, I had the ER learning mode set for crows foot only. Once I turned ER learning mode to "Off", the mandatory dot placement selection started working. While I will probably change it back to the role box side and crows foot, I will at least know what to look for next ...

  • ORM Sample Population Editor Import/Export

    I have found the Sample Population Editor to be an extremely useful feature for testing. However, much of my test data often comes from spreadsheet or delimited text files (comma or tab deliminated). Manual entry of the data becomes most tedious. Some means of entering the data (i.e., cut/paste or import/export) would be most useful.  Richard
