“This new edition is brighter, shinier, more complete, more pragmatic, more focused than the previous one, and I wouldn't have thought it possible to improve on the original. As the field of software architecture has grown over these past decades, there is much more to be said, much more that we know, and much more that we can reflect upon of what's worked and what hasn't—and the authors here do all that, and more.” —From the Foreword by Grady Booch, IBM Fellow Software architecture—the conceptual glue that holds every phase of a project together for its many stakeholders—is widely recognized as a critical element in modern software development. Practitioners have increasingly discovered that close attention to a software system's architecture pays valuable dividends. Without an architecture that is appropriate for the problem being solved, a project will stumble along or, most likely, fail. Even with a superb architecture, if that architecture is not well understood or well communicated the project is unlikely to succeed. Documenting Software Architectures, Second Edition, provides the most complete and current guidance, independent of language or notation, on how to capture an architecture in a commonly understandable form. Drawing on their extensive experience, the authors first help you decide what information to document, and then, with guidelines and examples (in various notations, including UML), show you how to express an architecture so that others can successfully build, use, and maintain a system from it. The book features rules for sound documentation, the goals and strategies of documentation, architectural views and styles, documentation for software interfaces and software behavior, and templates for capturing and organizing information to generate a coherent package. New and improved in this second edition: Coverage of architectural styles such as service-oriented architectures, multi-tier architectures, and data modelsGuidance for documentation in an Agile development environmentDeeper treatment of documentation of rationale, reflecting best industrial practicesImproved templates, reflecting years of use and feedback, and more documentation layout optionsA new, comprehensive example (available online), featuring documentation of a Web-based service-oriented systemReference guides for three important architecture documentation languages: UML, AADL, and SySML

We are a nation in process, we have the tools to excel to greater heights. For some of those that confronted our shores in the late 19th and early 20th century, you are either unaware of this country foundation or unconcerned of it's undead roots. There is a spirit in this land that still awaits its resting place.

The foundation of any software system is its architecture. Using this book, you can evaluate every aspect of architecture in advance, at remarkably low cost -- identifying improvements that can dramatically improve any system's performance, security, reliability, and maintainability. As the practice of software architecture has matured, it has become possible to identify causal connections between architectural design decisions and the qualities and properties that result downstream in the systems that follow from them. This book shows how, offering step-by-step guidance, as well as detailed practical examples -- complete with sample artifacts reflective of those that evaluators will encounter. The techniques presented here are applicable not only to software architectures, but also to system architectures encompassing computing hardware, networking equipment, and other elements. For all software architects, software engineers, developers, IT managers, and others responsible for creating, evaluating, or implementing software architectures.

This is the first full-length study of Jan Morris, one of Britain's foremost travel essayist and popular historians. It takes a critical look at a unique writer who after spending more than forty years as a man, underwent a sex-change in the 1970s and became a woman. The book outlines Morris's early life and education as James. It focuses on his early journalistic career when in 1953, as The Times correspondent, he took part in the British conquest of Everest and scooped the world with his reports. Morris's writings span nearly fifty years. Since the 1950s she has been a major figure in journalism and travel writing in both Britain and the United States. This book examines her writing technique and the style she uses in evoking the spirit of a place. It looks at her talent as a prolific author of romantic and imaginative prose in such books as The Matter of Wales, The Presence of Spain and Venice. As a historian she is best known for her trilogy on the British Empire, Pax Britannica, a powerful reconstruction of the empire and an enduring work of literary history. The book also looks at her most recent work Fifty Years of Europe. For those coming fresh to Jan Morris, it provides an introductory overview of her style - of the unique and peculiar words she uses - and her ability, through descriptive and imaginative prose, to capture the spirit of a place.
