DDD support in Qi4j explained
Domain Driven Design has a special status in Qi4j, and its tactical bits are embraced in Qi4j itself. These includes Entities, Services and Values. In Rickard’s blog entry Qi4j and state modeling, he covers these topics in a relatively easy to understand and pedagogic format. A highly recommended read for people who want to get a quick overview of what Qi4j is really about.
