JAOO 2007, Day 2

Day two starts with a keynote from Eric Meijer where he talks a bit what are his expectations of LINQ: relieve the developer from complicated tasks such as data access and concurrent algorithms. Was a nice talk but nothing new (but he showed the demo of 3D animation in DHTML).
The next talk from Jean Bezivin about model transformation. Was a bit boring in the first half because of the explanation how the OMG MOF meta-metamodel works. The second half was about the Eclipse Model Discovery project which was definitely more interesting.
Eric Evans talked about Strategic Design after lunch. His conclusion was that you have to find out the core model of the domain and focus your whole work primarily on this part. You should get rid of the supporting or generic domain models by buying COTS solutions our outsource the development. To find the core model is context depended and it is mostly not known by the management or the business. You as architect are responsible to work it out.
Klaus Marquardt was on the stage a second time and talks who you can identify complexity inside projects, what you can do no to get more as necessary and how bad are most metrics for measurement (especially senseless KPIs).
Joseph Yoder presents how he models most of his complex domain models with the Adaptive Object Model Pattern. This was especially interesting because I used the pattern in the no so far past and currently for some highly flexible models.
At last we visited the talk of Jimmy Nilson where he shows how he intends currently to use LINQ for Domain Driven Design. Nothing new here but the guy from Microsoft who developed the SQL implementation has told us something about the design decisions and trade offs of his team.
