Functional and Reactive Domain Modeling
Functional and Reactive Domain Modeling by Debasish Ghosh, published by Manning on October 24, 2016, is a comprehensive guide that explores the principles of domain modeling through the lens of functional programming. This first edition spans 320 pages and is presented in English. The book focuses on how to conceptualize domain models using pure functions, providing a framework for building larger abstractions essential for modern reactive systems.
Readers will find a methodical introduction to domain modeling techniques applicable to reactive architectures, even if their systems are not purely reactive or functional. The content includes discussions on relevant concepts of functional programming and reactive design patterns, along with practical examples that illustrate the application of these principles. Topics such as data modeling, software development, and systems analysis are woven throughout, making this book a valuable resource for those familiar with functional programming and traditional domain modeling, particularly using the Scala language.
Official synopsis Publisher
Summary
Functional and Reactive Domain Modeling teaches you how to think of the domain model in terms of pure functions and how to compose them to build larger abstractions.

About the Technology
Traditional distributed applications won’t cut it in the reactive world of microservices, fast data, and sensor networks. To capture their dynamic relationships and dependencies, these systems require a different approach to domain modeling. A domain model composed of pure functions is a more natural way of representing a process in a reactive system, and it maps directly onto technologies and patterns like Akka, CQRS, and event sourcing.
About the Book
Functional and Reactive Domain Modeling teaches you consistent, repeatable techniques for building domain models in reactive systems. This book reviews the relevant concepts of FP and reactive architectures and then methodically introduces this new approach to domain modeling. As you read, you’ll learn where and how to apply it, even if your systems aren’t purely reactive or functional. An expert blend of theory and practice, this book presents strong examples you’ll return to again and again as you apply these principles to your own projects.
