Exposing the not-so-secret practices of the cult of DDD
summary
Demystifies concrete DDD tactics and shows what actually changes code: use C# records and value objects (personal-number, color examples) to encapsulate validation and immutability; prefer intent-revealing methods over setters; hide DB int IDs and map them in Entity Framework; isolate integration via an anti-corruption layer; prefer hexagonal/ports-and-adapters; use domain events and CQRS for eventual consistency; solve DB+message atomicity with the outbox pattern while handling at-least-once delivery.
