Compared to strategic domain-driven design tactical design is much more hands-on and closer to the actual code. It is an approach for architecting software design by looking at software in top-down approach. The term of Domain in DDD has isA relationship to Problem Domain and often seems the same thing.

Entities are the first natural place we should aim to place business logic in domain-driven applications. DDD values domain expertise where decision depends on how much we understand the problems and how we choose the right path from initial to winning states. DDD – The Domain Driven Design – Bounded Context.

A repository implementing the example from the book Domain-Driven Design. In domain driven design entities and value objects can exist independently. Microsoft spain – DDD N Layer Architecture.

But in some cases the relation can be such that an entity or VO has no value without its context. Domain Driven Design Der Hauptfokus liegt auf der Domäne und deren Logik Komplexität wird durch ein Model sichtbar gemacht Domain Experts und Entwickler verfeinern das Model iterativ Aus dem Model entsteht der Code. These models encapsulate complex business logic closing the gap between business reality and code.

We create these representations with a concept called Model Driven Design. Context Domain Model Ubiquitous Language are basic concepts in DDD. The models and surrounding architectural mechanisms may be in various states of flux as the are refined over time.
