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.

He then proceeded with some criticism of dynamically typed languages [...]

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

CQRS made easy with cqrs4j

 

Command Query Responsibility Segregation (CQRS) is an architectural style that makes a clear distinction between commands, which tell an application to do something, and queries, which are requests for information from an application. This distinction comes from the fact that the requirements (and thus also the model) for the execution and validation of commands [...]
