How do you explain DDD?

Domain-driven design is the idea of solving problems of the organization through code. The business goal is important to the business users, with a clear interface and functions. This way, the microservice can run independently from other microservices.

What is DDD architecture?

Domain-driven design (DDD) is an approach to developing software for complex needs by deeply connecting the implementation to an evolving model of the core business concepts. Its premise is: - Place the project's primary focus on the core domain and domain logic. - Base complex designs on a model.

What is DDD in development?

Domain-driven design (DDD) is an approach to developing software for complex needs by deeply connecting the implementation to an evolving model of the core business concepts.

What is DDD used for?

Emphasizes Domain Over Interface: Since DDD is the practice of building around the concepts of domain and what the domain experts within the project advise, DDD will often produce applications that are accurately suited for and representative of the domain at hand, as opposed to those applications which emphasize the ...

When should I use DDD?

DDD provides sound software development techniques that address both strategic and tactical design. Strategic design helps us understand what are the most important software investments to make, what existing software assets to leverage in order to get there fastest and safest, and who must be involved.

Who is enforcing the business operations in DDD?

  • In DDD business operations/rules are enforced in Entities, Value Objects and Domain Services. The orchestrators , i.e. who is executing the business operations, are the Application Services.

When do you use domain events in DDD?

  • In other words, and using DDD terminology, use domain events to explicitly implement side effects across multiple aggregates. Optionally, for better scalability and less impact in database locks, use eventual consistency between aggregates within the same domain. What is a domain event?

How to create a unit of work in DDD?

  • The Unit of Work sits in the Infrastructure layer and will use the DBContext object as well but, unlike the repositories, it will only focus on transaction management, i.e. calling the SaveChanges () method. ? throw new ObjectDisposedException (this.GetType ().FullName);

Which is the correct way to implement DTO Using DDD principles?

  • The DTO implementation seems part of the Domain, but it means that when I create a collection of DTOs in the Service Layer and pass it to a Presentation Layer, I have to reference Domain Layer in Presentation Layer, which seems wrong. What is the correct way to implement DTO using DDD principles?
