Welcome

Welcome to our blog about all kind of topics that are related to software development. We blog about:

SOA, BPM, EDA, ECM and all the other buzz words. Beware some post might not be so common as you think. We are not scared to go against main stream thoughts.

Technologies like java, maven, springframework, OSGi and front end technologies and frameworks like jQuery, DWR, Flex.

Finally to make this happen we need tools and of course a Mac (well some of us do). So we blog about that as well.

Furthermore, we have also built a [...]

This distinction comes from the fact that the requirements (and thus also the model) for the execution and validation of commands are [...]

The power of immutability in a Rich Domain Model

As many other developers, I’ve been used to the fat service layer and the anemic domain model of the transaction script pattern. In that programming model, immutability is pretty much as rare as a Dodo. However, I have been investigating the rich domain model pattern lately (as you can read in my previous post) and [...]
