Are you on the same screen? Fine shades disappear if the screen brightness & contrast aren't set correctly, perhaps that's why you didn't see them?
[quote user="mnnoon"]I did try to install that tool but had some problems on my Windows machine.[/quote]
I tried to install it on Windows myself last September and it *was* awkward. I improved it quite a bit, but I need to go back and try it "from clean" again to see if I actually fixed the issues. I'd like to help you ...
Been doing the same thing for six years now... <https://github.com/cjheath/activefacts/tree/master/examples/norma>
I use several projects under one solution. In addition, each client gets their own solution, so as not to mix things up.
Marc, CQL is excellent for breaking large models down into small re-usable fragments. A project with a ...
[quote user="Ken Evans"]So with functional dependency, the hard work starts after you have established mega relation whereas with ORM, once you have agreed and validated the facts then you are finished.[/quote]
That would seem to be the result of applying the FD approach the way it's taught, but as i said before, that doesn't ...
[quote user="Ken Evans"]does the designer just arrange a series of interviews and ask each interviewee a series of questions?[/quote]
I don't usually do it that way, but some people do. You just ask people "tell me about your business" or "tell me how your business works" or even just "tell me ...
[quote user="Clifford Heath"]The mega-relation comes from the idea that everything we care about must be related in some way to all the other things. [/quote]
Sorry to quote myself here, but I should have continued that sentence with "otherwise we have two or more disjoint domains, and can choose which to model"
Matt, I'm sorry for implying that there was no solid plan in your merge approach; of course it's entirely systematic. I've just been bitten by it a number of times now, even when I thought I knew what I was doing, and it's in the nature of "being bitten" that I wasn't aware of what exactly had happened until later... ...
[quote user="Ken Evans"]The mega-relation must come from somewhere. It does not just appear out of thin air[/quote]
I see, that does make more sense.
The mega-relation comes from the idea that everything we care about must be related in some way to all the other things. At this starting point, there is no further structure. It's ...
Sigh. Again you mis-read and attribute thoughts that were not mine. It is never my goal, nor Widom's, to "end up with a mega-relation". She starts with one as a precursor to normalisation. It's this:
Apply(ID, name, campus, sport, HScode, HScity)
If I use FD, I would also start here, and follow the procedure she outlines ...
Note that while cross-model drag-and-drop is a very valuable and necessary feature in NORMA, I have seen numerous anomalies, specifically with NORMA bringing across many more objects than I selected, and where these conflict with the names, types, etc, of objects in the target model, simply changing the originals with no warning nor stopping for ...
