EventSourcing + CQRS: a light introduction

Data is at the core of any organization: the current state of an order, of social feeds, of a document is safely stored in ever evolving data storage systems. But working only the current state of the system we lose all the “whys” that drove the system in that state. EventSourcing tackles this point, changing the way in which we store data so that we persist information about the reasons of the evolution of the data in the system, and, together with CQRS, it enables a flexible system architecture able to cope with modern application requirements. In this talk I’d like to explain the basics of event sourcing and CQRS and how they fit in the bigger picture.
