CQRS and Event Sourcing

In 2008 I happened to work across the street from Greg Young who obviously is the inventor of CQRS. We ended up doing quite a lot of talking and one of the things that you know shook me awake from some of the behavior driven design or beat and specification by example here let me show you an even better way to do that. So it's kind of I wanted to to get back into something more rigorous so I got into obviously UML and the rational unified process and then agile, just always striving to find something to be better.
