NLayer Architecture in abp

Introduction

The layering of an application's codebase is a widely accepted technique to help reduce complexity and to improve code reusability. To achieve a layered architecture, ASP.NET Boilerplate follows the principles of Domain Driven Design.

Domain Driven Design Layers

There are four fundamental layers in Domain Driven Design (DDD):

  • Presentation Layer: Provides an interface to the user. Uses the Application Layer to achieve user interactions.
  • Application Layer: Mediates between the Presentation and Domain Layers. Orchestrates business objects to perform specific application tasks.
  • Domain Layer: Includes business objects and their rules. This is the heart of the application.
  • Infrastructure Layer: Provides generic technical capabilities that support higher layers mostly using 3rd-party libraries.

What is DDD?

ABP framework provides an infrastructure to make DDD based development easier to implement.

DDD is defined in the Wikipedia as below:

Domain-driven design (DDD) is an approach to software development for complex needs by connecting the implementation to an evolving model. The premise of domain-driven design is the following:

  • Placing the project's primary focus on the core domain and domain logic;
  • Basing complex designs on a model of the domain;
  • Initiating a creative collaboration between technical and domain experts to iteratively refine a conceptual model that addresses particular domain problems.

Layers

ABP follows DDD principles and patterns to achieve a layered application model which consists of four fundamental layers:

  • Presentation Layer: Provides an interface to the user. Uses the Application Layer to achieve user interactions.
  • Application Layer: Mediates between the Presentation and Domain Layers. Orchestrates business objects to perform specific application tasks. Implements use cases as the application logic.
  • Domain Layer: Includes business objects and their business rules. This is the heart of the application.
  • Infrastructure Layer: Provides generic technical capabilities that support higher layers mostly using 3rd-party libraries.
