What problem does it solve?

Domain-Driven Design (DDD) solves the problem of inconsistent business language and tangled models that make complex systems hard to evolve by aligning code structure with real domain concepts.

Core Features & Use Cases

• Ubiquitous language: Ensures code terms match what domain experts use to avoid “translation tax” across teams and modules.
• Bounded contexts and context maps: Defines where each term has one meaning, and documents how contexts relate to prevent accidental coupling.
• Tactical building blocks: Uses entities, value objects, aggregates, repositories, and domain events to enforce invariants and coordinate change safely within consistency boundaries.
• Use case: When you’re splitting a monolith into services, deciding aggregate boundaries, or handling cross-domain workflows triggered by meaningful business events.

Quick Start

Ask an AI to help you design bounded contexts and aggregate rules for your domain so that each concept has a single meaning and changes are coordinated via domain events.
