Clean Architecture

In this blog entry I give a primer on Clean Architecture, which is a modern, scalable formal software architecture which is appropriate for modern web applications. Next, I discuss how Domain-Driven Design fits into this picture, and how DDD concepts dovetail nicely into Clean Architecture, producing a methodology called Clean DDD. Finally, I introduce Command Query Responsibility Segregation (CQRS), and describe how it complements and enhances Clean DDD solutions to create software systems that are elegant, robust, scalable, and testable.

Domain Driven Design

What is Domain-Driven Design? It is a software design methodology which seeks to efficiently create business logic components and functionality from business requirements, typically by working closely with domain experts. In this entry, I give a brief overview of Domain-Driven Design (DDD) and discuss its importance in modern software development.
