See this olso on my blog: http://jroller.com/page/olaru Domain Driven Design and enterprise applications. I was very confused after read mister Erik Evans...
It seems as if XIC removes the duplicity problem (having domain behavior in two places: 1. orchestration and 2. within objects) by removing the domain...
I suppose that you could think of it that way, but it doesn't have to be. XIC's service mapping is an integration technology within heterogeneous enterprise ...
I think enterprise applications as you have described them would be anti-DDD. So the question is whether enterprise applications really do have to be defined...
Hi, DDD is easy to sell to architects and developers, but is more difficult to sell to business people (at least that's my experience so far). Does anyone on...
Hi, Business people should know about processes and information/resources - and the relation between them. (Otherwise they should do something else, like...
Well, it seems that business people find the Zachman Framework more interesting and useful than DDD from a business value perspective. I don't know much about...
To quote a famous trans-sovereign sweat shop: Just Do It! I have experience working with business SMEs (Subject Matter Experts) where over the course of a...
With apologies to John, Per, and Tomas, I have to differ. I don't think business people necessarily care about testing frameworks, architecture frameworks, or...
When using an OR mapper (JDO, TopLink, Hibernate) for persisting domain objects a special problem arises if you like to serialize the domain object. It's in...
... IMO, the value of DDD to business people rests in the emergence and reinforcement of the Ubiquitous Language on the development team, and the direct...
One solution to your problem is handled by JDO 2.0 fetch groups. You identify the fields that belong to a particular fetch group, optionally including ...
... [snip] ... Amen, Scott. I have seen this time and time again. Once developers and business people begin focusing on using the UL (Ubiquitous Language),...
... If I understand you correctly, it does not restrain the domain model at all. I am only familiar with Hibernate, but there you have three options: Lazy load...
Hi Torsten, ... I like this idea. You might generalize this further: objects should only hold object references to objects that contribute to their identity...
Well, selling DDD to business people is necessary in many cases because they usually control the budgets. If they are not convinced that doing strategic...
Oops.. that should of course be UL, not UB :-) ________________________________ Fra: domaindrivendesign@yahoogroups.com på vegne av Per Spilling Sendt: fr...
Jan, ... We are just building an intranet application which should replace a bunch of 2-tier PowerBuilder/C++ applications. We decided to use an n-tier...
... Ummm...will it? Why would I need to move the object around to do something with it? Why not ask the object in the first place, right where it is? Jan ... ...
Just want to clarify that with "business people" I don't mean domain experts. Domain experts usually have no problem understanding the value of "high level...
Hi, My point is that the object can be in another process and on another machine, and not "right where it is". Perhaps you have one application handling...
... Oh, I will use RMI. But therefore I have to serialize the domain objects to send them over the network to the client. And to serialize them, I have to...
