Use Cases
Where You Will Use This
From Algorithms to Systems
The framework expands from code to the shape of whole domains.
Domains and Their Language
The world the business creates, named in its own vocabulary.
Bounded Contexts as Worlds
Contexts draw lawful boundaries around meaning.
Aggregates and Invariants
Consistency is protected inside a boundary — not scattered across it.

Where It Fits
Where This Book Fits
Boundaries Are Decisions
A bounded context is not a folder in your repo. It is a lawful boundary around meaning: inside it, a term has one definition, one invariant, and one owner. Drawing that boundary is a proof obligation, not a preference.
Invariants in Production
When an invariant must survive across requests, transactions, and deployments, its boundary must be explicit. Aggregates keep the rule and the data that upholds it inside one wall.
