CQRS
An architectural pattern that separates commands (write operations) from queries (read operations). It is often used together with event sourcing and optimizes read performance through materialized views.

Event Sourcing is an architectural pattern that models system state as an immutable sequence of events, persisting the fact of every state change, with the current state derived by replaying all historical events in order; its advantages include a complete audit log, the ability to rebuild the state at any point in time, and the ability to fix projections or add new read models through replay, while the cost is that querying the current state requires aggregating events, and it is usually combined with CQRS and materialized views to optimize read performance.
In payment systems, the event store is usually separated from the write side (commands) and the read side (queries), forming a CQRS architecture.
This hybrid architecture concept is closely aligned with the Event Sourcing and CQRS patterns in the database field, where the authoritative source and the derived query structure are separated.
