DDD, CQRS and Event Sourcing... how do I actually DO it?

Now then, there's a lot of talk about DDD, CQRS, Event Sourcing going around. It's not a new idea or a difficult one to grasp when you actually get into it. Where suitable, applying DDD, CQRS and Event Sourcing can be lots of win.

You do tend to hear the same questions though:

  • "How do I cope with eventual consistency?"
  • "How do I run complex queries if my objects are stored as events?"

My goal is to answer them, and in the process demonstrate how might you actually go ahead and implement such a system - by demonstrating One I Prepared Earlier! Yes there'll be slides relating to DDD, CQRS and Event Sourcing, but the plan is to get the heck out of slides and into a sample implementation.

A deep dive it ain't, but hopefully getting to see something that works should prove that with very little effort you can implement these concepts.
