1. Modelling Heuristics

"How do you approach software modelling problems?”

When a client asked me about my mental process, I didn’t have a proper answer — yet. The question intrigued me. Do you need a propensity for modelling, or is it a learnable skill? I embarked on a mission to find modelling heuristics: the mental tools, that help us look at the problem from different angles; the little tricks to validate a model before we build it; the rules of thumb that lead us to iteratively refine our solutions. In this talk, I share some of the ideas I collected from books, from people I interviewed, and from my own experiences.

He’s the founder of the Belgian Domain-Driven Design community. Mathias lives in Kortrijk, Belgium, where he reads books, and invents crazy Lego structures with his two boys.

2. DDD, CQRS and ES: Lessons learned

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 her latest project 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.
