Is this a decision that holds?
How it keeps an audit trail and personal data compliant, how it is licensed and supported, and why it does not lock you in.
Audit and compliance by design
Every change is kept as it happened, and every event is chained to the one before, so the history can be audited – and personal data can still be handled as the GDPR demands.
This guide explains how to audit the integrity of events stored in EventSourcingDB.
Verifying Store IntegrityThis guide explains how to verify the internal integrity of an EventSourcingDB instance.
GDPR ComplianceThis guide explains how to assess and achieve GDPR compliance in event-sourced systems.
Open standards, no lock-in
Events in the open CloudEvents format, models in the open ESDM specification, and a landscape of products from many makers.
This guide explains what CloudEvents are, why they matter for event-sourced systems, and how the specification helps standardize event data across systems.
The ESDM SpecificationThe open language for event-sourced domain models, under the MIT license.
LandscapeThe products around Event Sourcing, CQRS, and Domain-Driven Design, from many makers.
MissionEvery system has a story, but most systems keep only its last page.
