What are the three layers of DDD applications?
I would say there are three distinct layers in DDD applications – the inner domain layer, the outer application layer, and the external world (includes the API/UI). The domain layer contains aggregates, entities, value objects, domain services, and domain events.
How does domain logic work in DDD applications?
In DDD-flavored applications, your domain logic lives mostly in the form of aggregates (and some bits in domain services). But that logic and object’s behavior is usually persistence-agnostic. It means that it is not our domain objects responsibility to worry how they are persisted.
How does DDD help you understand the complexity in the domain?
DDD patterns help you understand the complexity in the domain. For the domain model for each Bounded Context, you identify and define the entities, value objects, and aggregates that model your domain. You build and refine a domain model that is contained within a boundary that defines your context.
What do you need to know about DDD microservices?
Design a DDD-oriented microservice. Domain-driven design (DDD) advocates modeling based on the reality of business as relevant to your use cases. In the context of building applications, DDD talks about problems as domains.
How to design a DDD-oriented microservice in.net?
Domain-driven design (DDD) advocates modeling based on the reality of business as relevant to your use cases. A microservice’s application layer in .NET is commonly coded as an ASP.NET Core Web API project. The project implements the microservice’s interaction, remote network access, and the external Web APIs used from the UI or client apps
How does the domain model layer depend on infrastructure?
Most of all, the domain model layer must not directly depend on any infrastructure framework. The infrastructure layer is how the data that is initially held in domain entities (in memory) is persisted in databases or another persistent store.
