Enterprise Architecture A to Z: Frameworks, Business Process Modeling, SOA, and Infrastructure Technology, cost-effective to test trends in architecture planning, administration, and management. To establish a framework for discussion, this book begins by evaluating the role of Enterprise Architecture Planning and Service-Oriented Architecture (SOA) modeling. In particular, this book discusses the Open Group Architecture Framework (TOGAF) and the Zachman Architectural Framework (ZAF) in detail, as well as formal architecture standards and all four layers of this model: business architecture, information architecture, solution architecture, and technology architecture. The first part of the text focuses on the top layer of the architecture framework, while the second part focuses on the technology architecture.
