Hello, jcm list. I was wondering if there's a way to find out what all the constraints are that someone might conceivably want to incorporate into a conceptual...
Bob, ORM deals directly with these constraints: Mandatory Internal Uniqueness External Uniqueness SubSet Equality Exclusionary Frequency Ring Value (or...
Thanks, this is interesting, particularly the distinction between value and set constraints. To get back to my original question, if anyone knows of any...
Bob, Question - Are you trying to determine if two conceptual models have overlapping facts and constraints - or a mismatch of same facts and conflicting ...
Hello I am trying to find out if there is a single modeling/repository tool or suite, from a single vendor, that will meet my needs, or if I will need to look...
I found an extensive list of constraints in an article: Jianyang Zhou, "Introduction to the Constraint Language NCL [Natural Constraint Language]", The Journal...
Shayne, We have done models for most every DBMS in ORM. There are a couple of solutions. However, they are not direct at this time. Today ORM only shows...
You may also visit the Ron Ross Business Rules site for more constraints. They are listed, but I find the notation to be overwhelming. Pat Patrick Hallock Sr....
Thanks, it sounds good. (My company is a division of Reed Elsevier, so hopefully that will help me get access!) Some web searches have turned up constraint...
Shayne, Have you looked at Microsoft's Visio for Enterprise Architects? This is a special version of Visio that is only available as part of the Visual Studio...
Hi Ted I have looked at the Visio for Enterprise Architects, but it is highly unlikely that our organization will buy the whole Visual Studio .NET Enterprise...
Shayne, I think it unlikely the other tools will do an ORM model directly. However, I do believe an XML Schema that can feed other modeling tools is highly...
Hi Shayne, I think it's unfortunate that Microsoft chose to package the ORM modeling features in a version of Visio that is *only* available as part of VS.NET...
Shayne, The VS.Net platform will be tightly integrated with the Rational suite of applications. So your question about the support of Rational and ORM is...

Hi Pat I am certainly looking forward to advanced XML interfaces for information models, but I am not certain this will solve my problem. In order for me to...
... Dang straight! Some of us work strictly in MS Access and SQL Server. Who needs C-/+/#, etc? Sheesh! Guess we'll have to visit the computer shows and look...

I guess instead of "multiple conceptual models" I should have said "multiple conceptual modeling systems," i.e. if X is all of the constraints that ORM can...
Bob Good question and a good research project. As an aside, I like to call it a "Data Modeling Scheme" rather than "system." but you are right it is not a data...

Thanks Gordon! By the way, I'm not trying to badger the list by asking the same question over and over--I have no idea how that e-mail, which I originally sent...
Bob: I agree; your project seems interesting. I don't know the exact nature of your project, so I cannot tell if what I am about to say will interest you, but...
Joe makes some good points, but I have some qualifications. A key distinction to make is between the expressiveness of a graphical language and that of a...

I concur with Scot. A related issue is the general notion of information hiding. Sometimes you don't want to see all the rich variety of constraints that are...

All, Maybe a little of the topic but not too far: A modeler/reviewer/user can not only hide the constraints, but also hide facts themselves by not placing them...
I wanted to follow up on a key point that Terry made, which is the ability to populate every fact in ORM and check the population with the user. I have used...

Does anyone know if there is an upgrade path from Viso 2000 Enterprise Edition to whatever the modeling tool is called in VS? I would'nt mind getting VS in...
Yes, you can upgrade to VS .NET Enterprise Architect from Visio Enterprise 2000 for US$1799 (instead of paying the full $2499). Here is the site for more...
