say when DDD pays off and what it is.

الموضوعات المخطط لها

• DDD models the business domain in code, with developers and domain experts working together.
• Strategic DDD: language, bounded contexts, context maps. Tactical DDD: entities, value objects, aggregates, repositories, events.
• It pays off where rules are complex and change often; it is overkill for plain CRUD.
• Symptom it fixes: an anemic model, where entities are data bags and services hold all the rules.
• Shop's Order has rules (status flow, cancellation) but only getters and setters.
