Because components belong to specific layers in the architecture, other layers can be mocked or stubbed, making this pattern is relatively easy to test. This book provides in depth coverage of large scale software systems and the handling of their design problems. Architectural patterns are similar to software design pattern but have a broader scope. Each phase is itself composed of a series of steps. The architecture of a system describes the systems overall organization into components and connections between those components. Each view addresses a set of system concerns, following the conventions of its viewpoint, where a viewpoint is a specification that describes the notations, modeling, and analysis techniques to use in a view that expresses the architecture.
