Expert guidance for implementing Command Query Responsibility Segregation (CQRS) and Event Sourcing patterns to build scalable, auditable systems with complete historical tracking and optimized read/write models.

Command Query Separation Separate operations that change state (commands) from operations that read state (queries).

| Express intent (CreateOrder, UpdatePrice) | Return data, never change state | | Can be rejected (validation failures) | Can be cached and optimized | | Return success/failure, not data | Multiple models for different needs | | Change system state | Eventually consistent with writes |
