• Bounded Contexts: Explicit boundaries around domain models.
• Analysis Model: Translating domain knowledge into code.
• Identity: What makes an entity unique.
• Invariants: Business rules that must always hold true.
• Changing State: How state transitions work in a domain.
• Streams: Event streams and their role in the architecture.
