Figure 2-1 Two localities and a connection
Connection
Connections are defined as generalized physical linkages. Connections are characterized by what they carry or transmit and the necessary performance and quality attributes in order to specify their physical realization at the design level. They are linked to the concept of a flow port in SysML, which allows the designer to specify what can flow through an association and its ports (data, power, fuel).
In UML, connections are represented by stereotyped associations.
Design points
MDSD is intended to provide a framework for reasoning about the whole spectrum of systems concerns.
Four basic principles
MDSD provides support for constructing a sound architecture on the basis of four principles: separation of concerns, integration, system decomposition, and scalability.
