What Is a Bounded Context?

A bounded context is an explicit boundary in domain-driven design within which a single model and its vocabulary stay internally consistent. The same word can mean different things in two contexts, so each owns its own definitions and rules. Drawing these boundaries keeps large systems from collapsing into one tangled, contradictory model.

Why it matters

Without clear boundaries, shared terms drift and models leak into each other, creating coupling and bugs. A bounded context makes integration points explicit so teams can evolve their slice of the system independently.
