14	Out of curiosity.... Is anyone out there finding data modeling projects using UML? I realize that it is picking up steam as a application level modeling ...	Scot A. Becker scotb@...	Feb 4, 1999 3:59 pm
15	I do not know of projects using exclusively UML for data modeling. We are using ORM & UML in parallel to define the structure of our data, thanks to Dr....	Allred, Mark J Mark.Allred@...	Feb 4, 1999 5:09 pm
16	... Interesting. Do you have any sort of set process? Like first you do the ORM model, derive and ER schema, and transform that in to a class diagram? Or is it...	Scot A. Becker scotb@...	Feb 4, 1999 5:22 pm
17	Mark - ORM can also be used to capture and document the big picture. See the article by Dr. Halpin entitled "Conceptual Schemas with Abstractions - Making...	dennis_corbo@...	Feb 4, 1999 7:58 pm
18	How could it be that UML would supplant anything in modeling 'persistence'? If anything, UML's treatment of data modeling seems to me a hole in the barn big ...	Drew Georgopulos DrewG@...	Feb 4, 1999 8:13 pm
19	We have not established a good process. We are groping for a way to synchronize application and database designs. The ORM was already developed, so our...	Allred, Mark J Mark.Allred@...	Feb 4, 1999 8:22 pm
20	... I think a lot of people are attracted to it as it is a common technique between app modeling and data modeling. However, from a data standpoint, it isn't...	Scot A. Becker scotb@...	Feb 4, 1999 8:22 pm
21	I am finding in reverse-engineered InfoModeler ORM diagrams of a database schema what appears to be a mandatory role constraint dot, except that it is open...	Allred, Mark J Mark.Allred@...	Feb 5, 1999 2:55 am
22	This no doubt due to unfamiliarity and 'still learning', but I felt that using UML to describe the data tier was lacking in the specificity or, maybe just my...	Drew Georgopulos DrewG@...	Feb 5, 1999 6:42 pm
23	I don't have the book handy, so treat this as a stab in the dark, but wasn't the open dot an older or alternative notation for disjunctive mandatory ...	Drew Georgopulos drewg@...	Feb 5, 1999 6:47 pm
24	... Not quite. I think the symbol you are thinking about is the one for relative closure, which is supposed to be a square, not filled in, and is placed where...	Scot A. Becker scotb@...	Feb 5, 1999 6:58 pm
25	Whoops! Right you are Scott! Pretty scary when somebody else knows what you're thinking better than you do! <g> Thanks. drew mail to: drewg@... ...	Drew Georgopulos drewg@...	Feb 5, 1999 7:21 pm
26	My book is in Chicago, but I think relative closure applies only to unaries. It is reflects the "open world" vs "closed world" assumption. Under the closed...	Bill MacLean bmaclean@...	Feb 5, 1999 9:06 pm
27	Well, my fishing trip isn't producing any trout. Thank you all for your efforts. Here is a bit more bait: The mandatory role constraint tool will remove the...	Allred, Mark J Mark.Allred@...	Feb 5, 1999 10:44 pm
28	Alfred It sounds like it might be a minor bug with the drawing part of the interface. Please send Chang a copy of the actual model so he can look at it. Thanks...	Terry Halpin TerryH@...	Feb 8, 1999 10:02 pm
29	The February issue of the Journal of Conceptual Modeling (JCM) is now online at http://www.inconcept.com/JCM/. In this issue of the JCM, Dr. Terry Halpin gives...	Scot A. Becker scotb@...	Feb 12, 1999 3:18 am

31	Are there any methods/products that handle process modeling as well as ORM handles data modeling? When I start a new project my data architect (me) starts on...	logic@...	Feb 16, 1999 8:29 pm
32	Rose and RUP cover the method, the process, the diagrams, tie scenarios back to objects and in general does everything BUT what ORM does. Personally, I am...	Drew Georgopulos DrewG@...	Feb 16, 1999 10:20 pm
33	Hi Kelly Various ORM-based methods have been proposed for process modeling, but none of these has been standardized or refined in the way the data modeling...	Terry Halpin TerryH@...	Feb 16, 1999 10:20 pm
34	To me, that's the major benefit of ORM, there is no taceability issue for analysts, because the user helps you fill in the example data, and there's no...	Drew Georgopulos DrewG@...	Feb 16, 1999 10:20 pm
35	Visio Enterprise supports both ORM and UML. It actually supports more of UML than Rose does (e.g. check out Activity Diagrams). UML can't express many ORM...	Terry Halpin TerryH@...	Feb 16, 1999 10:51 pm
36	I've tried combining Visio and InfoModeler but it requires transcribing the objects from IM into UML classes then applying the use cases. Not very efficient...	logic@...	Feb 17, 1999 3:23 pm
37	Visio Enterprise supports all of UML 1.2, but Visio Professional supports only a small fragment of it. There's a free 60-day test drive of Enterprise available...	Terry Halpin TerryH@...	Feb 17, 1999 5:15 pm
38	Just to clarify. Visio currently has no plans to integrate ORM with the core of Visio. We are, of course, interested in providing much deeper support for ORM...	Anthony Bloesch AnthonyB@...	Feb 17, 1999 5:52 pm
39	Hello Anthony, We list members should feel lucky to have such a distinguished pair (by 'pair' I am of course also referring to Terry) of ORM gurus and Visio ...	Scot A. Becker scotb@...	Feb 17, 1999 6:10 pm

43	I re-read "Program in the Problem Domain" (Section 32.5) in "Code Complete". McConnell uses abtraction as a programmer's device to reduce complexity. By ...	Kelly VanDusen logic@...	Feb 19, 1999 12:41 am
