More Information
  • Utilize arc42 to document a system's physical infrastructure
  • Learn how to identify a system's scope and boundaries
  • Break a system down into building blocks and illustrate the relationships between them
  • Discover how to describe the runtime behavior of a system
  • Know how to document design decisions and their reasons
  • Explore the risks and technical debt of your system

When developers document the architecture of their systems, they often invent their own specific ways of articulating structures, designs, concepts, and decisions. What they need is a template that enables simple and efficient software architecture documentation. arc42 by Example shows how it's done through several real-world examples.

Each example in the book, whether it is a chess engine, a huge CRM system, or a cool web system, starts with a brief description of the problem domain and the quality requirements. Then, you'll discover the system context with all the external interfaces. You'll dive into an overview of the solution strategy to implement the building blocks and runtime scenarios. The later chapters also explain various cross-cutting concerns and how they affect other aspects of a program.

  • Get to grips with leveraging the features of arc42 to create insightful documents
  • Learn the concepts of software architecture documentation through real-world examples
  • Discover techniques to create compact, helpful, and easy-to-read documentation
