CQRS as a Junior Developer
Fresh from university, searching for a development job, having one within two weeks. And at an interesting company at that. That is what happened to me about a year ago. So, you could (and probably should) call me a junior developer. After a month of trainings and new experiences I was put on my first […]

Tutorial – Getting started with CQRS and Axon Framework
Axon Framework greatly simplifies building CQRS based Event Driven architectures in Java. Such an architecture provides very powerful options in terms of application scalability and extensibility. In this tutorial, I want to go though the process of setting up a basic application architecture with the Axon Framework.

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 […]
CQRS – Designing domain events
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 […]
