Overview of this book

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.

VI.1 Introduction and Goals

The need to deliver an arc42 solution architecture in different formats was the primary driver that gave birth to docToolchain. As a technical person, I saw the value of text-based documentation. However, other stakeholders wanted to have the documentation:

  • "Where all other documentation is"—in a wiki
  • "How we always document"—with MS Word
  • "In a revision-safe format"—as PDF

Soon, after fulfilling these needs, I noticed that it's quite hard to update changing UML diagrams. "Couldn't this be automated?," I thought to myself and created the exportEA task as a simple Visual Basic Script.

I didn't plan docToolchain on a drawing board. Instead, it evolved in an agile way; that is, through the requirements of the users.

Together with Dr. Gernot Starke, I gave a talk about this approach, and received some interesting feedback from the audience, such as "… but I don&apos...
