Domain-Driven Design

Overview

This skill provides guidance for domain modeling based on Rich Hickey's data-oriented design principles and Scott Wlaschin's type-driven design approach. Focus on building systems that make illegal states unrepresentable, prioritize data and transformations over objects and methods, and establish a ubiquitous language that bridges technical implementation and business domain.

Core Principles

Rich Hickey's Data-Oriented Design

Simplicity over Ease

• Favor simple constructs that can be understood independently
• Avoid complecting (intertwining) unrelated concerns
• Separate policy from mechanism, data from behavior
