  • Re: The Stuff of Thought

     Sorry.. not on subject.. but I've been eyeing the kindle for a little while. How do you like it? The price seems just above what I think it should be but I am strongly considering purchasing one.

    I purchased a Kindle version of the book from Amazon. I am enjoying this book. The examples are really down the earth. I would also recommend the book to people interested in semantics from childhood - on to my old age. Patrick Hallock

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

     Ken, I appreciate the thoughtful reply. I don't think the core question is knowing what is meant by a correct conceptual model. I apologize if somehow I called that into question. Let me back up and try to describe just the function of what I imagine SchemaCop to do.. it is helpful if you have used FxCop, as that is a parallel concept as ...

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

    Hi, Sorry I'm finding difficulty in understanding the functions of what you call "SchemaCop". As I see it, a physical model is "merely" an encoding of a set of facts. The facts may be wrong (not in conformance with the reality of the domain they are supposed to represent), or meaningless (making statements such as ...

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

    Ken, thanks for your reply. I did manage a couple reverse engineerings of physical dbs using VEA, and it seemed to do an OK job at it. The issue comes in the fact that often the physical model is far removed from the original intent conceptually. This happens usually because there is a lack of a conceptual model, poor data modeling skills, changes ...

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

    You mention VEA. Did you ever get around to using the reverse engineering feature in VEA? It would be nice to validate against SQL Queries but, as I see it, the rubber meets the road when you allow non-technical domain experts to see the "real meaning" of the data model from which their physical database is constructed.  It seems ...

  • Validation of a physical model against a conceptual model

    I've been working a little on the idea of an application called SchemaCop.. which is to be for physical database models what the .NET application FxCop is for the .NET framework. I think anyone who has experienced working with an existing data model in the majority of cases will face models that lack normalization, referential integrity, and ...

  • Re: Marking a post/reply as answer

    Admin, Looks like the post marking system is working, and I've marked several posts (in threads I started), as answered.  I think the arrangement should work for most forums here, but more so where specific questions are asked (NORMA - Technical, for example).  A forum like "Issues" may be better left to ...

  • Re: Richmond

    Hi Victor, I'm glad that we have come to an amicable agreement based on understanding. Thanks for your patience. Regarding "advertising" - Yes, I could quite easily switch on advertising and get a little bit of income. The reason that I don't do such things has to do with my purpose for creating, maintaining and ...

  • Re: Richmond

    Hi Ken, Okay, okay. I concede. In another life I would have been a lawyer. I certainly have enough paranoia to ask the probing questions! You do well to to see me for what I am, harmless but shrewd. Certainly I get to know you this way and visa versa. That's a shame about the the effort required. That's pretty harsh. To be honest, it ...
