Bounded Context
Bounded Context
A bounded context is a concept from Domain-Driven Design that establishes boundary within a domain and contains models related to that context. The concepts, entities, value objects, and aggregates within the bounded context are written using a ubiquitous language. This language is also used in things such as documentation for the project and spoken throughout meetings on the project.
A domain may have multiple bounded contexts within its environment. Each bounded context may be maintained by a team. Context Mapping is used to help explain the relationships between two bounded contexts as well as indicate the relationship needed between the teams that maintain those two contexts.
