Command Query Responsibility Segregation (CQRS) pattern

I’ve just read excellent introduction to the Command Query Responsibility Segregation (CQRS) pattern. And you know, it seems really worthy to have in a toolbox.
Actually just to be ready to use it I’ll need to research many related patterns such as Reporting Database, Event Sourcing, etc..
So check it yourself - read this great CQRS introduction to see how many useful patterns and practices those are related to CQRS you don’t know yet ;)
