商品描述

This is a practical guide for software developers, and different than other software architecture books. Here's why:

It teaches risk-driven architecting. There is no need for meticulous designs when risks are small, nor any excuse for sloppy designs when risks threaten your success. This book describes a way to do just enough architecture. It avoids the one-size-fits-all process tar pit with advice on how to tune your design effort based on the risks you face.

It democratizes architecture. This book seeks to make architecture relevant to all software developers. Developers need to understand how to use constraints as guiderails that ensure desired outcomes, and how seemingly small changes can affect a system's properties.

It cultivates declarative knowledge. There is a difference between being able to hit a ball and knowing why you are able to hit it, what psychologists refer to as procedural knowledge versus declarative knowledge. This book will make you more aware of what you have been doing and provide names for the concepts.

It emphasizes the engineering. This book focuses on the technical parts of software development and what developers do to ensure the system works not job titles or processes. It shows you how to build models and analyze architectures so that you can make principled design tradeoffs. It describes the techniques software designers use to reason about medium to large sized problems and points out where you can learn specialized techniques in more detail.

It provides practical advice. Software design decisions influence the architecture and vice versa. The approach in this book embraces drill-down/pop-up behavior by describing models that have various levels of abstraction, from architecture to data structure design.

商品描述(中文翻譯)

這是一本針對軟體開發人員的實用指南,與其他軟體架構書籍不同之處在於:

- 它教導風險驅動的架構設計。當風險較小時,不需要過於細緻的設計;當風險威脅到你的成功時,也不能藉口設計草率。本書描述了一種只做足夠架構設計的方法。它避免了一刀切的流程陷阱,並提供了如何根據面臨的風險調整設計工作的建議。

- 它使架構普及化。本書旨在使架構對所有軟體開發人員都有意義。開發人員需要了解如何將限制條件作為確保期望結果的引導軌道,以及看似微小的變化如何影響系統的特性。

- 它培養宣告性知識。能夠擊中球和知道為什麼能擊中球之間存在著差異,這是心理學家所稱的程序性知識和宣告性知識。本書將使您更加意識到自己一直在做什麼,並為這些概念提供名稱。

- 它強調工程。本書專注於軟體開發的技術部分,以及開發人員為確保系統運作所做的工作,而不是職稱或流程。它向您展示如何建立模型並分析架構,以便您可以做出有原則的設計折衷。它描述了軟體設計師用於解決中到大型問題的技術,並指出您可以在哪裡更詳細地學習專門技術。

- 它提供實用建議。軟體設計決策會影響架構,反之亦然。本書的方法採用了深入/彈出行為,通過描述具有不同抽象層次的模型(從架構到資料結構設計)來實現。
