Overview

Domain-Driven Design focuses on modeling software based on the business domain, using ubiquitous language, bounded contexts, and strategic patterns to manage complexity.

<aside> ℹ️ Why It Matters: Understanding Domain-Driven Design is essential for building robust, scalable, and secure modern applications.

Key Concepts

[x] Ubiquitous Language - Shared vocabulary
[x] Bounded Contexts - Clear boundaries
[x] Entities - Objects with identity
[x] Value Objects - Immutable objects
[x] Aggregates - Consistency boundaries
[x] Domain Services - Domain logic
[x] Repositories - Data access abstraction
[x] Domain Events - Communicate changes
