Excerpted from Domain-Driven Design Book
Definition: A representation of the
Bounded Contexts involved in a project and the actual relationships between them and their models.
Problem: People on other teams won't be very aware of the
Context bounds and will unknowingly make changes that blur the edges or complicate the interconnections. When connections must be made between different contexts, they tend to bleed into each other.
Solution: Identify each model in play on the project and define its
Bounded Context. This includes the implicit models of nonobject-oriented subsystems. Name each
Bounded Context, and make the names part of the
Ubiquitous Language.
Describe the points of contact between the models, outlining explicit translation for any communication and highlighting any sharing.
Map the existing terrain. Take up transformations later.
