For a long time, I have been in several conferences talking about one of my favorite topics: software design and DDD. As usual, I start asking how many have heard about DDD? The answer is unanimous, the vote changes when I go to the second question: How many of you have used DDD properly? The answer usually goes to none of the people or only a few people. So, why do we have a vast number of people knowing DDD, yet only an exception can apply it correctly? To solve this point, I wrote this book to help you. Many teams struggle to implement DDD effectively in real-world projects. The root of the issue is quite simple: although these patterns are well recognized, their purpose is frequently misunderstood or overlooked. This book aims to bridge that gap, not only by explaining what DDD is but also by guiding how to apply it effectively, starting with the reasoning behind it. This book begins by exploring the foundational reasons for the existence of DDD. By understanding its strategic principles, developers can avoid common—and often costly—implementation mistakes. Many books on DDD assume that readers are already convinced of its value; this one takes a step back to build that foundational understanding, incorporating insights from other authors and complementing them with practical examples and real-life experiences. This book avoids dogma, combining established theory with modern use cases to help you make better design decisions tailored to your specific context. To guide you through this journey, the book is structured into three parts. The first part lays the strategic foundations of DDD, emphasizing the importance of comprehending the domain, collaborating with business experts, and organizing systems using concepts like bounded contexts and context maps. This section is intentionally placed at the outset because mastering strategic DDD is essential for preventing misalignment and overengineering later on. Once that foundation is established, the second part transitions into the tactical aspects of DDD, where design meets implementation. You will learn how to model aggregates, encapsulate business rules, and apply DDD across various architectural styles, including monoliths, microservices, and distributed systems. This section also features a chapter focused on testing and validation, helping you maintain your model’s integrity and expressiveness over time. The final part of the book synthesizes all the concepts by examining how to integrate DDD into real-world enterprise environments using tools like Jakarta EE, Spring, Eclipse MicroProfile, and Quarkus. It also addresses advanced design practices, including code-level decisions and anti-patterns to avoid. The book concludes with a reflection on domain storytelling—a technique designed to help teams build shared understanding and bridge the gap between business and technology.
