Domain-Driven Design — Bounded Contexts in Practice
Learn ubiquitous language, bounded contexts, and aggregates — the DDD concepts that actually matter for working developers.
Domain-Driven Design is a 500-page book that most developers either never read or read and found too abstract. The irony is that the most valuable ideas in DDD are the simplest ones — and they solve problems every developer faces.
This lesson focuses on the three DDD concepts that deliver the most practical value: ubiquitous language, bounded contexts, and aggregates. These are the tools that help you design systems that mirror how your business actually works, rather than how your database happens to be structured.
The Problem DDD Solves
Consider a typical e-commerce platform. The word "product" means different things to different teams:
- Catalog team: A product has a name, description, images, categories, and SEO metadata
- Inventory team: A product has a SKU, warehouse
