ES, CQRS & DDD: Lessons learned and walls bumped into DDD, CQRS and Event Sourcing are all based on simple principles. Yet, using them on a project brings with it big challenges and new ways of thinking. In this session Gitte will give you the real life story of how DDD, CQRS and ES was used on one of her latest projects and how she bumped into quite some walls while doing it. You will get an overview of the basic buildup of the application and of the points of most friction. Gitte will also try and give some solutions to the problems the project team went through.
