Today, I released version 0.6 of the Axon Framework. 0.6 has many new features and is another step towards full production readiness. There is still some work to do, but first, let’s take a look at what has changed… Continue reading Axon Framework 0.6 released
Besides some changes to existing building blocks, such as the event bus, which is now much more powerful, the 0.5 version also includes some new features. Read on to find out more.

Events play a major role in this architecture, and the way you design these events greatly influence the extensibility of [...] 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 are significantly different than those for queries. Events play an important role in the synchronization of application state resulting from executed command. Applying a CQRS style architecture involves the development of quite a lot of “plumbing” code: event dispatching, asynchronous event processing, transactions, etc. cqrs4j, an Apache 2 licensed open source framework, takes care of all the plumbing for you. Read on to find out how… Continue reading CQRS made easy with cqrs4j A couple of things happened to me over the past few days as I was taking on a new role within a new project that caused me to ponder a bit about the role of domains and domain driven development (DDD) within the drive towards service oriented architectures (SOA). The result of these ponderings was, as it often is in my case, that the more we think things change, the more they stay the same. And the more we think we learn, the more we find we already knew what we have learned. Continue reading SOA and the domain: how new technology should not blind you to old wisdom |
