Domain-driven design

1 Day
Online or on-site

This hands-on workshop is a practical introduction for developers and architects who wish to discover the basic ideas behind CQRS & Event Sourcing and how those patterns leverage Domain-Driven Design. We start off with a basic CRUD service for a social network as we gradually apply a combination of CQRS and Event-sourcing patterns while enforcing basic DDD principles.
