On March 1st, Erik Rozendaal will give a presentation about Command Query Responsibility Seggregation (CQRS). Greg Young, one of the masterminds behind CQRS, has confirmed that he will be present during this meetup too. Seems like a good recipe for an interesting evening.
Attendance is free, but registration is required. Read on for details.
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.

Command-Query Responsibility Segregation (CQRS) is slowly but steadily gaining ground as an architecture that helps developers to develop scalable, extensible and maintainable applications. Events play a major role in this architecture, and the way you design these events greatly influence the extensibility of your application.
In this post, I describe some CQRS event basics and design considerations that help keep your application extensible.
One of the main things we do @ jteam is creating rock solid custom development. Of course we use proven frameworks, we keep innovating and we use a lot of the best practices for custom software development. Best practices I am talking about are: Continuous Integration, Test Driven Development, Peer reviews and of course Scrum. I guess I could use more buzz words in there, but that is not the scope for this item. So I am not going to talk about cloud, soa, virtualisation to name a few. This post is about why DDD is a match made in heaven with custom development.
In Alef’s previous blog entry about the JTeam Technology Matrix, he explained the basic idea of using a BCG-matrix to classify technologies. In this blog entry I’ll focus on the ‘Star’ section of our current matrix and highlight some of the technologies that are currently in there. Star technologies are the technologies that bring us added value in the projects that we do, but are also cool and innovative to use. Please keep in mind that the content of the matrix is under constant discussion and is subject to change. This overview should therefore be considered a snapshot of today’s matrix.
