Where NOT should you start The typical developer path when thinking about DDD is jumping into code. Code samples and demos are great for illustrating patterns or concepts. The problem is when patterns… Read More »DDD is just giving a 💩 about your Domain

Are you frustrated that you have to open multiple files across multiple layers to make what seems like a simple change? One of the culprits for this is following structure and templates that apply patterns or concepts to solve problems you might not have. One typical case of this is using aggregate from domain drive design. In this video, I’ll give examples of where an aggregate can make sense and where it’s not and adds useless indirection.

Should you use Domain Driven Design?

I often read comments about how Domain Driven Design is too complicated or overkill. Then there are others new to DDD that want to apply it, especially the technical patterns, everywhere. So the question is, should you use Domain Driven Design? The answer is somewhere in the middle. Let me explain.
