It's great to see some traffic on this list. :-) Student is a role played by a person - correct. It is never a moment-interval. A Student might enroll for a...
Thank you for your answer!:) Regarding the student question... When you refer to the term "student" do you mean the general term (the student role!) or a...
In David's example there would be three classes on the diagram: a Person (green), a Student (yellow), and an Enrollment (pink). In your later example, the...
Hi David, ... Agreed, ... Not so sure here. From analysis point of view yes, but from a design stand point not so sure ... ... In a domain you might find for...
Hi Gyula, ... I suggest you to have a look at the Event Sourcing pattern to capture events from the mobile system. ... I understand the need to preserve older...
I'm not authorized to go into details, so I try other but similar samples. 1. Say you have a weather forecasting company. You run a central system which stores...
Hi, here's another question that stands up at least for me:) What is the color modeling statement about business vs. system roles? How do they corressponds to...
Nuno, I can't disagree with your post. You are clearly very good at color modeling. However, I would caution against mixing implementation detail with...
... Agreed. That is the beauty of DNC and SOM Patterns. They help discovering the domain to great detail, not leaving one rock unturned. ... I'm very...
Hi Gyula ... I would say you need both the data and the rules lead to such decision. ... If it is functional business requirement belongs to analysis as much ...
Yes! It makes sense:) Storing events (eg. the changes, the deltas) is a nifty approach. I think this approach also relates to non-functional apsects of the...
... True. But you can use rolling snapshots. But the question is how many times you need to dig in to the far past to find justifications for a business...
The rolling snapshot is a nifty idea:) Regarding the banking example I see your opinion (at least I think so). Processing operative data (actual rules) and...
Hi For brief introduction to historic values and snapshots see http://www.step-10.com/SoftwareDesign/ModellingInColour/HistoricValues.html For a brief...
I'm going out in the limb here. There are far more proficient people reading this list then me so they may correct me any time. Price is usually a value object...
Try this. Consider Security and Business are usually distinct concern. Depending on organization security is even manage by a different department then say...
Hi Nuno -- Try starting with Product (description), in blue of course, rather than a (thing). That description may include certain "fixed" value attributes...
PS, Nuno -- I just saw Palmer's message... [Date: Oct 28, 2009 10:40 AM] Start with his first link, on "Historic Values" ...and keep reading. Steve -- you...
Roles and security can become a big topic, and it can be very difficult to generalize. Basic, generic access control that determines who can access which...
Thanks for the input Ken. ... It depends on the domain. In a warehouse all products have an SKU so product is this context is a thing. Yet for cataloguing, UPC...
Hi Nuno -- For any ID *unique-to-instance* of some Product, then, yes, I'll "go green." -- Examples: S/N's on computers, appliances, etc.; VIN's on vehicles;...
Hi Steve, I've been following for a long time your work and David on DNC and FDD. At least since 2003 when I was asking questions about DNC on the FDD site to...
Hi Nuno Thanks for the feedback, maybe I need some better examples in this case. I agree models have to be viewed in light of their context, and too broad a...
I for one enjoyed and appreciated your response. I feel that might thoughts run closer to yours now and that gives me some assurance :) When looking for domain...
Having left Micro Focus last month, means I have left behind the Together modeling tool too. While I wait for whatever is next, I have started to look...
I think a modeling tool should support iterative development and remember "versions" of a model created after each iteration, be able to show these versions...
One more thing: I've found RAVEN FLOW to be an interesting tool, too. Though I've never used it in real life projects, just seen the demo of it I think it is...
