Command Query Responsibility Segregation (CQRS) is a powerful concept that has the potential to make for reliable and maintainable systems. It is also broadly misunderstood and means different things to different people.

Derek Comartin learned about the idea after viewing some talks by Greg Young and has since successfully applied the approach with great success and it has transformed the way he views features, business requirements, and dependencies. The result is a system that is easier to maintain and faster to enhance. Among his key lessons are that slices are better than layers, mediators improve dependency management, and cohesion is better applied to business concerns than to technical ones.

In this episode, Derek joins Dave Rael for a conversation about CQRS and applying it to make your code your own and to separate it from technical concerns in order to make your software development operation work better and faster.
