Functional and Reactive Domain Modeling

<Descriptions>

 Biographical Note:

Debasish Ghosh is a software architect with extensive experience in domain modeling. Debasish uses Scala and Akka in his daily work and was one of the earliest adopters of event sourcing using EventSourced, now called Akka Persistence. He's the author of DSLs in Action, published by Manning in 2010.

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.

What's Inside

    Real-world libraries and frameworks
    Establish meaningful reliability guarantees
    Isolate domain logic from side effects
    Introduction to reactive design patterns

About the Reader

Readers should be comfortable with functional programming and traditional domain modeling. Examples use the Scala language.
