About this area
Command Query Responsibility Segregation (CQRS) is an architectural pattern that separates read and write operations for a data store into distinct models. Commands mutate state and produce events; queries return data optimized for the read side. CQRS is frequently combined with Event Sourcing, Domain-Driven Design (DDD), and message-based integration to scale complex domains. The pattern is most associated with Greg Young, building on Bertrand Meyer’s Command-Query Separation principle, and is widely covered in writings by Martin Fowler and the Microsoft Patterns and Practices team.
