Enterprises, from small to large, evolve continuously. As a result, their structures are transformed and extended continuously. Without some means of control, such changes are bound to lead to an overly complex, uncoordinated and heterogeneous environment that is hard to manage and hard to adapt to future changes. Enterprise architecture principles provide a means to direct transformations of enterprises. As a consequence, architecture principles should be seen as the cornerstones of any architecture. In this book, Greefhorst and Proper focus on the role of architecture principles. They provide both a theoretical and a practical perspective on architecture principles. The theoretical perspective involves a brief survey of the general concept of principle as well as an analysis of different flavors of principles. Architecture principles are regarded as a specific class of normative principles that direct the design of an enterprise, from the definition of its business to its supporting IT. The practical perspective on architecture principles is concerned with an approach to the formulation of architecture principles, as well as their actual use in organizations. To illustrate their use in practice, several real-life cases are discussed, an application of architecture principles in TOGAF is included, and a catalogue of example architecture principles is provided. With this broad coverage, the authors target students and researchers specializing in enterprise architecture or business information systems, as well as practitioners who want to understand the foundations underlying their practical daily work.

"The rules of architecture have been discussed since the Roman architect and engineer Vitruvius coined the trilogy firmitas, utilitas and venustas, most commonly translated as firmness, commodity and delight. Put simply, this means that a building should stand up and endure, that it should serve its function, and that it should give pleasure to its users and the wider community. Great buildings, like great art, contain something that is impossible to define or pin down. But that greatness, in almost all cases, overlays the principles set out in this book. While one cannot guarantee that a building will be great, if all the principles are followed, you will avoid the pitfalls to which too many are subject. This new title in our 10 Principles series provides clear explanations of each tenet along with useful illustrations to help the reader visualize what is being discussed. The author assumes no background on the subject, but an interest in learning more about what goes into making a building work. An experienced writer on this subject, Ruth Slavid provides a useful and illuminating primer to the field that is accessible to students of architecture, architects or architectural historians or anyone interested in the principles behind the buildings that surround them."

The rapid evolution of technical capabilities in the systems engineering (SE) community requires constant clarification of how to answer the following questions: What is Systems Architecture? How does it relate to Systems Engineering? What is the role of a Systems Architect? How should Systems Architecture be practiced?A perpetual reassessment of c

Presents an approach to software architecture that takes organizational issues into consideration. The approach uses a series of five principles--vision, rhythm, anticipation, partnering, and simplification--to reveal hidden risks and opportunities of software architecture. Complementing these principles are criteria, patterns, and antipatterns. The criteria help assess how well each principle is being performed currently, and the patterns and antipatterns provide guidance on how to apply the principles. c. Book News Inc.

Philosophy exercises a massive influence on contemporary architectural culture and the understanding of the built environment. Discussions of architects and architectural academics are heavily loaded with theoretical ideas, concepts and views imported from the works of philosophers. At the same time this architectural employment of philosophy rarely goes beyond the tendency to mine philosophical works for ideas, words and phrases and use them, often without much understanding, in order to promote architectural agendas and embellish theoretical claims made by architects and academics. The book presents the history of this phenomenon for the past hundred years. It describes and analyzes numerous, often funny, entertaining as well as embarrassing, examples of false intellectual pretense and pompous but incompetent philosophical posturing by prominent architects and architectural academics of the era and their efforts to bamboozle readers, colleagues and the general public. The book presents a powerful criticism of modernist views on architecture and argues that the rise of obfuscation and philosophical posturing among architects and architectural academics is a defensive strategy intended to draw attention away from the failure of Modernism in architecture.

The Elements of Architecture is a clear and well structured introduction to sustainable architecture, which concentrates on general principles to make an accessible and comprehensive primer for undergraduate students. The author takes a fresh and logical approach, focusing on the way aspects of the built environment are experienced by the occupants and how that experience is interpreted in architectural design. He works through basic elements and senses (sun; heat; light; sound; air; water and fire) to explain and frame effective environmental architectural design - not only arguing that the buildings we inhabit should be viewed as extensions of our bodies that interact with and protect us from these elements, but also using this analogy to explain complex ideas in an accessible manner.

In-depth examination of concepts and principles of Web application development Completely revised and updated, this popular book returns with coverage on a range of new technologies. Authored by a highly respected duo, this edition provides an in-depth examination of the core concepts and general principles of Web application development. Packed with examples featuring specific technologies, this book is divided into three sections: HTTP protocol as a foundation for Web applications, markup languages (HTML, XML, and CSS), and survey of emerging technologies. After a detailed introduction to the history of Web applications, coverage segues to core Internet protocols, Web browsers, Web application development, trends and directions, and more. Includes new coverage on technologies such as application primers, Ruby on Rails, SOAP, XPath, P3P, and more Explores the fundamentals of HTTP and its evolution Looks at HTML and its roots as well as XML languages and applications Reviews the basic operation of Web Servers, their functionality, configuration, and security Discusses how to process flow in Web browsers and looks at active browser pages Addresses the trends and various directions that the future of Web application frameworks may be headed This book is essential reading for anyone who needs to design or debug complex systems, and it makes it easier to learn the new application programming interfaces that arise in a rapidly changing Internet environment.
