Concept Map of the Domain Driven Design Context Mapping for Strategic Design Patterns

Diagram

Description

Shows the patterns of context mapping for strategic design and their relationships.

Concepts

Concept	Description
Anti-Corruption Layer	The anti-corruption layer is an architectural layer to separate the domain model from outside models. It enables the domain model to access the data of the outside model as expected by the domain model. In a clean architecture, an adapter is the place to implement the anti- corruption layer by mapping the outside model to the domain model.
Big Ball of Mud	A Big Ball of Mud is a casually, even haphazardly, structured system. Its organization, if one can call it that, is dictated more by expediency than design. Yet, its enduring popularity cannot merely be indicative of a general disregard for architecture.
Bounded Context	A descrition of a boundary (typically a subsystem or the work of a particular team) within which a particular model is defined and applicable.
Conformist
Context Map	The context map provides an overview for all models and their boundaries and interfaces.
Customer/Supplier	A clear relationship between two teams, where the downstream team is the customer of the upstream team.
Open Host Service	An open protocol that gives access to your subsystem as a set of services.
Partnership	A partnership between the teams in charge of the two contexts, when the teams will succeed or fail together.
Published Language	A well-documented shared language that can express the necessary domain information as a common medium of communication, translating as necessary into and out of that language.
Separate Ways	A bounded context with no connection to the others at all, allowing developers to find simple, specialized solutions within this small scope.
Shared Kernel
