  • Fact missing in relational view / ER

    &nbsp;I&#39;ve put together a model to express scheduling, one particular fact is as follows: &nbsp;WeeklySpecificationSettings has DaysOfWeek. It is possible that more than one WeeklySpecificationSettings has the same DaysOfWeek and that the same WeeklySpecificationSettings has more than one DaysOfWeek. In each population of ...

  • Re: Rapid Fact Type Establishment - Richmond

    I like it.. it&#39;s an enhancement to working with the visual representation.. I do find that making key combinations available for tasks like establishing a fact between selected entities is something worth having. It&#39;s tough to beat really good textual fact entry though for speed. Have you considered a keystroke / auto-labeling scheme for ...

  • Re: ORM for a WFF?

    &nbsp;Thank you everyone for the replies. I think from the suggestions I have enough reading to do for the rest of the year and then some! I will definitely be looking at the nORMa meta model and I will look at some of the papers on the brcommunity site. While my current &quot;rule engine&quot; project isn&#39;t endeavoring to handle all of the ...

  • Re: ORM for a WFF?

    Thanks for the additional information Ken. Victor.. I cant race you.. my finish line keeps moving all over the place! ;) The subject is overwhelming. I am moving along I think with some limited knowledge.. I have a question relating to binary predicates and sets for anyone willing to entertain it. My first stumbling block is that for a binary ...

  • Re: ORM for a WFF?

    &nbsp;Brian, &nbsp;The book title &quot;Introduction To Logic&quot; got me digging through a series of books on mathematics that I had aquired five or six years ago.. and I found the single book I had bought on logic.. called &quot;Introduction To Logic - And To The Methodology of Deductive Sciences&quot;. If only buying books that I wanted to ...

  • Re: ORM for a WFF?

    Thanks Brian and Ken. Brian, I will definately try to put some ORM fragments together as I begin to understand where to start.. at this point I am trying to understand based on my goals, which system of logic I should be concentrating on. I first found propositional logic, but in reading today I have drifted towards and believe that I will focus ...

  • ORM for a WFF?

    I wasn&#39;t sure which forum would be best to post this in.&nbsp; I am teaching myself about formal logic.. with the catalyst being that I am creating a &quot;Rule Engine&quot; of sorts.. I want to approach defining a &quot;rule&quot; as a well formed formula.. hoping to create a relational schema to store those definitions. So I was wondering ...

  • Re: Validation of a physical model against a conceptual model

    &nbsp;Ken, I think ideally option 2 would be the route taken. In my own experience, when I am tasked with assisting an organization improve their data model, the first step for me is to work with the domain experts to develop a solid conceptual model, following the CSDP as much as possible. As for there being ambiguities between the formal ...

  • Re: Validation of a physical model against a conceptual model

    Ken, I tried to edit my last post to add this, for some reason it would not take the update. I wanted to answer your question: &quot;Is SchemaCop intended to&nbsp;test for question 1, 2, 3, 4 or some of them or all of them....&quot;, at the moment I am focused on a tool to assist in answering the question posed by item 4. I think the other ...
