A system comprises multiple views such as planning, analysis, design, implementation, deployment, structure, behavior, input data, and output data views. Since structure and behavior views are the two most prominent ones among multiple views, integrating the structure and behavior views is an approach for integrating multiple views of a system. In other words, structure-behavior coalescence (SBC) results in the coalescence of multiple views. Therefore, it is concluded that the SBC architecture is a synonym for systems architecture. This book focuses on the SBC architecture which consists of a) SBC architecture description language (SBC-ADL), b) SBC view model (SBC-VM), and c) SBC architecture development method (SBC-ADM). Systems architecture is on the rise. By this book’s penetrating introduction and elaboration, all readers shall understand clearly how the SBC architecture helps systems architects effectively perform architecting, in order to productively construct fruitful systems architectures.
