Build auditable systems by storing complete history of state changes as immutable events rather than current values.
You are designing a system requiring auditability, temporal analysis, or replay capability. Event sourcing provides complete history and enables powerful event-driven architectures. Read domain requirements and existing event-driven patterns.
Based on Greg Young's event sourcing work and CQRS patterns:
Identify Core Events: What state changes matter? Order placed, payment received, shipment dispatched. Each event is fact about domain; captured in past tense.
Design Event Schema: Each event contains timestamp, aggregate ID, type, data. Include enough context to understand intent (who, when, why).
Plan Aggregate Boundaries: Group related events into aggregates. Order aggregate: contains all events for single order. Enables consistent snapshots and replay.
Implement Snapshot Strategy: Full replay from beginning gets slow. Snapshot order state every 100 events; replay only from last snapshot. Balance storage and speed.
Create Read Projections: Maintain materialized views (current-state, analytics) from event stream. These are caches; can be rebuilt from events anytime.
