Give each bounded context its own model and words
ARC-74Split the code into bounded contexts, such as billing, catalogue and shipping. Each context has its own module, its own types and its own glossary, and other contexts use only its public entry point.
Change an aggregate only through its root
ARC-75Group objects that must stay consistent together into an aggregate, such as an order and its lines. Outside code changes them only through methods on the root, which check every business rule.
Change one aggregate per transaction
ARC-76Save one aggregate per database transaction. Refer to other aggregates by their ID, and update them afterwards through events.
Translate outside models at the boundary
ARC-77Convert the types of every outside system into your own types in one adapter module. Examples are a payment provider, a legacy app or another context. No other code imports the outside types.
