So what is all the fuss about? Domain-Driven Design, or DDD, is an approach to help us succeed in understanding and building software model designs. It provides us with strategic and tactical modeling tools to aid designing high-quality software that meets our business goals. More importantly, Domain-Driven Design is not about technology.

I make websites. Sometimes I make music. Over the years, I’ve noticed an interesting pattern of behavior from some musicians—often self-taught—who think of themselves as creative types: they display an aversion to learning any music theory. The logic, they say, is that knowing the theory behind music will somehow constrain their creative abilities. I’ve never understood that logic (and I secretly believe that it’s a retroactive excuse for a lack of discipline). To my mind, I just don’t see how any kind of knowledge or enlightenment could be a bad thing.
