What is Domain-Driven Design?

Domain-Driven Design (DDD) is a software development approach that connects complex business domains with technical implementation. By creating a shared language between business experts and developers, DDD helps teams build software that accurately reflects business needs and can evolve with changing requirements.

Ubiquitous Language

A shared vocabulary between technical and domain experts

Bounded Contexts

Explicit boundaries between different parts of the domain

Strategic Design

Techniques for large-scale structure and integration

Tactical Patterns

Implementation patterns for expressing domain models in code

Why DDD Matters

In today's complex software landscape, traditional development approaches often fail to address the heart of business problems. DDD provides a framework for tackling complexity at its source—the business domain itself—resulting in software that's more maintainable, adaptable, and aligned with business goals.

Reduced translation errors between business requirements and technical implementation
Improved communication between technical and non-technical stakeholders
More maintainable and adaptable software architecture
Better alignment between software capabilities and business needs
Faster response to changing business requirements

Domain-Driven Design with PHP

Introduces the design patterns of DDD. Originally published in 2018 and thus a bit outdated, but still widely read.

"Although it is important and instructive to know, understand, and practice using the patterns presented, the design patterns focus on implementation and not on the particularly important strategic part of Domain-Driven Design (DDD). DDD is more than just a collection of design patterns."

Ketchup or Mayo

It can't be difficult to open a French Fries stand, you say? Turns out: yes, it is. There are no trivial domains, after all.

"There are no simple business models when it comes to software. The closer you look, the more worlds open up. And there are unanswered questions everywhere. The biggest mistake you can make now is to go ahead and develop software without a solid understanding of the business model and business processes."
