Hi Frans, I see the following aggregates on your analysis (provided that we start the modeling from the DB, which is not my preference): Order (with...
Hi Carlos, ... I was talking about the relational model, so at the level of NIAM/ORM, not about tables etc. though in the case of northwind they're the same. ...
Tomas, [Just a lot of code like custmerVO.setName(customerORM.getNmae()). I don't recommend anyone to do that trip!] I would like to hear more of your problems...
Hi Frans, ... I haven't saw, in the domains I worked on, the need for a relation from Product to OrderDetail (the M:N relation you mention), I used a relation...
The first place to start is going to be Eric Evans book. After that things start to get a little hazy. Unlike gregory I strongly recommend against reading...

Hi Joe, ... I don't think your little utility manages the entities in the system, saves graphs in one go, provides an OO, compile time checked filtering system...
Frans, Thanks for following up. ... The original post from Casey said, "This tool will generate entity classes for each table in the database." He then asked...
Thanks for the insight. It is interesting to see how your experiment evolved. As I was revisiting DDD book, I realized Eric's notes about "Who sets the ...
Hi everybody, first of all I want to say thank you to this group, your experiences, insights and ideas are exceptional. I've seen lots of rumblings of people...
Frans, I don't think that the Northwind database problem model is complicated by repositories. The repositories and aggregates are there to help not to hinder...
Frans, I think something is missing here.You are trying to model a domain off of an ER model without even looking at how the data will need to be used by an ...
