To tackle these challenges, a three-dimensional process of founding architecture is proposed
(depicted in Exhibit P.1 along with corresponding architecture discipline attributes): conceptual
architecture, logical architecture, and physical architecture. As illustrated, the conceptual
architecture discipline is concerned with three fundamental ingredients: technical generalization,
metaphorical application, and taxonomy establishment. The logical architecture provides guidance
to addressing asset utilization and reuse, functional solutions, and architecture strategies.
Last, the physical architecture elaborates on physical addressing, non-functional solutions, and
business continuity. These architectural components are further discussed in the next sections and
elaborated on in details in Chapters 15 and 16.
The physical architecture is the resulting tangible architecture construct that is typically
regarded as a nonmodeling discipline and thus not discussed in detail in this book.
SERVICE-ORIENTED CONCEPTUAL ARCHITECTURE MODELING
The service-oriented conceptual architecture modeling discipline offers mechanisms to describe
the proposed technological solution (discussed in Chapter 15). These best practices focus on
the generalization aspects of the technological environment and the participating service-oriented
software entities that collaboratively provide solutions. Another focus is employing architectural
metaphors that depict software components??™ functionalities and their ability to collaborate.
