Domain-driven Design: Tackling Complexity in the Heart of Software

Incorporate effective domain modeling into the software development process

Software design thought leader and founder of Domain Language, Eric Evans, provides a systematic approach to domain-driven design, presenting an extensive set of design best practices, experience-based techniques, and fundamental principles that facilitate the development of software projects facing complex domains. Intertwining system design and development practice, this book incorporates numerous examples based on actual projects to illustrate the application of domain-driven design to real-world software modeling and development.

• Domain Model: Part I outlines the goals of domain-driven development, defines terms, and gives an overview of the implications of using the domain model to drive communication and design
• Model-Driven Design: Part II condenses a core of best practices in object-oriented domain modeling into a set of basic building blocks and focuses on the kinds of decisions that keep the model and implementation aligned with each other, each reinforcing the other’s effectiveness
• Refactoring: Part III delves into modeling principles that can guide choices along the way, and techniques that help direct the search
• Strategic Design: Part IV explores a triad of principles that apply to the system as a whole: context, distillation, and large-scale structure

 Throughout the book, discussions are illustrated not with over-simplified, “” problems, but with realistic examples adapted from actual projects. With this book in hand, object-oriented developers, system analysts, and designers will have the guidance they need to organize and focus their work, create rich and useful domain models, and leverage those models into quality, long-lasting software implementations.

 “The book is a fun read. Eric has lots of interesting stories, and he has a way with words. I see this book as essential reading for software developers―it is a future classic.”

―Ralph Johnson, author of Design Patterns
