Recently, I released Axon Framework 1.0. Instead of it being an opportunity to take a small break, things have gone into a higher gear instead. In this article, I give a sneak preview of what’s coming up in and around Axon Framework. Continue reading Coming up in the Axon Framework 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
Read on to find out more. Continue reading Axon Framework – the CQRS framework for Java – version 0.4 released 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 Is has been more than a month a go that we had our first meeting, it is shorter than a month before we have the second event. The next event will take place on the 27th of october. The program for the event will be: 17:30 – 18:30 pizza at JTeam office 18:30 – [...]
A lot of activity in the DDD area, and a lot of discussions with colleagues and other interested people about DDD. The biggest question is of course WHY?. There is not a very simple answer to this question. Ok, maybe one: Why not?. But that is to easy and not very convincing. A lot of arguments against DDD are coming from people talking about implementation problems. This blog post is focussing on those people. Not that others should not read it, but I am writing this post with those people in my mind. Continue reading Introduction to DDD for the implementation oriented Implementing an equals method in Java can be quite complicated. Fortunately there are numerous document around the web with useful tips, hints and frameworks to assist you in this process. However, an implementation of the equals method that is technically correct doesn’t have to make any sense functionally. In Domain Driven Design, your domain model implementation is the beating heart of your application. Everything has to make perfect (functional) sense in there. Having good equals methods is of vital importance there. In this article, I will elaborate on some common pitfalls you can encounter when implementing the equals method, as well as some sensible guidelines. Continue reading Domain Driven Design and the equals method Today we release the website of a new User group for all Domain Driven Design enthusiasts. This user group is meant to facilitate all experienced DDD people to unity and share ideas/experiences. We also would like to help starters getting up to speed learning more about DDD What are we planning to do? We [...] |

Last week, I published the 0.4 release of the Axon Framework. Axon helps developers build high performance, scalable and extensible applications using the CQRS pattern. The 0.4 release is a major step towards 1.0, and includes transactional event handling, high-performance caching repositories and easy configuration of event sourcing support. Furthermore, we have also built a demo application that uses Flex to get real-time updates pushed from the server.
Regular readers of gridshore know that Allard and I have attended a training on DDD (Domain Driven Design) and that we have started a user group for
