It Was Never About the Database

- Event sourcing shifts focus from technical database details to improving team collaboration and business process visibility.
- Traditional CRUD applications obscure business processes by only storing current state, making it hard to trace how events led to that state.
- Modeling business events (e.g., 'PaymentFailed') creates a shared language that bridges gaps between domain experts and developers.
- Event sourcing exposes organizational misalignments by forcing teams to agree on event names and definitions during modeling sessions.
- The real value of event sourcing lies in the shared understanding and language it creates, which persists in the system's events and code.
- Event-based workshops (e.g., Event Storming) surface hidden assumptions and edge cases, leading to better-aligned software and business needs.
- The database in event sourcing serves as infrastructure to support the story of business events, not just efficient data storage.
