#bounded contexts

In the world of software development, creating robust and efficient applications requires more than just writing code. It involves understanding the complex interactions between various components and aligning the software’s design with the real-world domain it serves. This is where Domain-Driven Design (DDD) comes into play. In this article, we’ll explore what Domain-Driven Design is, its key…

Clean Architecture + Bounded Contexts diagram

I’m happy to release a two Clean Architecture + Bounded Contexts diagrams into the public domain (CC0 1.0).

I created these diagrams for Wikimedia Deutchland with the help of Jan Dittrich, Charlie Kritschmar and Hanna Petruschat. They represent the architecture of our fundraising codebase. I explain the rules of this architecture in my post Clean Architecture + Bounded Contexts. The new diagrams…

Clean Architecture + Bounded Contexts

In this follow-up to Implementing the Clean Architecture I introduce you to a combination of The Clean Architecture and the strategic DDD pattern known as Bounded Contexts.

At Wikimedia Deutschlandwe use this combination of The Clean Architecture and Bounded Contexts for our fundraising applications. In this post I describe the structure we have and the architectural rules we follow in the…

Generic Entity handling code

In this blog post I outline my thinking on sharing code that deals with different types of Entities in your domain. We’ll cover what Entities are, code reuse strategies, pitfalls such as Shotgun Surgery and Anemic Domain Models and finally Bounded Contexts.

Why I wrote this post

I work at Wikimedia Deutschland, where amongst other things, we are working on a software called Wikibase, which is…

Notes: Implementing DDD, chapter 2

Notes from Implementing Domain Driven Design, chapter 2: Domains, Subdomains and Bounded Contexts (p58 and later only)

User interface and service orientated endpoints are within the context boundary

Domain concepts in the UI form the Smart UI Anti-Pattern

A database schema is part of the context if it was created for it and not influenced from the outside

Contexts should not be used to divide…
