  • Re: Which solution/project types?

     Hi Paul, Before you can use an object-role modeling file with Visual Studio, you have to install NORMA. (Downloadable from the library) Then, if you want to create a new .orm file in Visual Studio, you use File>New>File, scroll down the list and click on "Object-Role Modeling file. If you want to use an existing ...

  • Re: Subtypes

    There are two stages in making subtypes in NORMA. The first stage is to make sure that you are using the ORM subtype paradigm to think about your Universe of Discourse(UoD). The ORM subtype paradigm is based on sets and membership of sets. Terry's 2008 book discusses this and this website has an introduction. ...

  • Re: Relational View - different display formats?

    Hi Marc, As Terry mentions in his book, Clive Finkelstein developed the Information Engineering notation and it was later popularised by James Martin with whom I used to do TV shows.  As we discussed offline, James gave me a copy of his original IE documentation. In 1989, James published IE in three books that may still be available ...

  • Re: Relational View - different display formats?

     Hi Marc,Regarding Information Engineering, page 320 in Terry's 2008 book contains a 1:1 mapping between some aspects of IE notation and ORM. You can also change some aspects of the ORM notation by choosing from the Visual Studio>Tool>Options>Entity Relationship Learning Modes.   Ken

  • Re: Iterative modelling – how to differentiate between confirmed and drafts part of model

    Hi Kim,  Here are some suggestions: Context Make sure that everyone understands that when you create a object-role model, what you are doing is : 1: Asserting that some facts are true and then modeling the common structures as a fact type. 2: Limiting the permissible populations of the fact types by adding constraints (also ...

  • Re: Reverse engineering - from MySQL database to ORM 2 model?

    Hi Marc, "I was wondering if it is possible to reverse engineer an existing MySQL database to an ORM 2 model? Is this possible? If yes, is there a document/ tutorial about it?"  Yes - you can reverse engineer MySQL into ORM2. There are two methods that come to mind: 1: Directly into NORMA Start NORMA using the DB Import ...

  • Re: RDF and OWL and Visual OWL

     Hi Alan, Thanks for your questions. I have never used Visual OWL so I will need time to look into it. Regarding question 5, my University of Liverpool MSc Dissertation has never been published. However, I plan to include it with the book that I am writing - which I estimate will be published in mid 2016. The dissertation document ...

  • Re: Non Visual Studio version of Norma

     Hi Hugh,I agree with you about the value of ORM. However, as you may know, NORMA is Visual Studio extension and uses many of the facilities built into Visual Studio.I'm fairly sure that the effort required to port NORMA to another platform would be "substantial" and I don't know of any plans to do ...
