arc42 by Example: Software Architecture Documentation in Practice, 3rd Edition

This book contains several real-world software architectures, documented with the practical arc42 template. You will learn about the inner workings of a chess engine, a huge CRM system, a cool web system to track biking activities and an extremely small menu-bar application. Each of the examples starts with a brief description of the problem domain, including the quality requirements, before we explain the system context with all the external interfaces. Then we dive into an overview of the solution strategy to prepare you for the implementation building blocks and runtime scenarios (as major architectural views). Later on we explain the crosscutting concepts of every architecture and its implementation. You will learn that documentation can be compact, helpful and easy-to-read. Status Decemter 2022: We just started editing a new and enhanced edition of the book. Ever reader will get this new version (our third edition) as a free update, of course!
