A.3. Target Architecture for the TRRS

The target architecture for the TRRS is described in UML and organized according to the Open Distributed Processing (ODP) standard. As described in other parts of the book, ODP is a standard conceptual framework for object-oriented architectures [ISO 96]. The ODP framework provides a separation of design forces for managing the complexity of large-scale distributed architectures. ODP is quite flexible, and its flexibility is utilized to advantage in this example. For example, not all viewpoints are architecturally significant for this example, so we selectively exclude those viewpoints that are not necessary for the purpose of this system.
