Functional and Reactive Domain Modeling teaches readers how to think of the domain model in terms of pure functions and how to compose them to build larger abstractions. It begins with the basics of functional

programming and gradually progresses to the advanced concepts and patterns needed to implement complex domain models. The book demonstrates how advanced FP patterns like algebraic data types,

typeclass based design, and isolation of side-effects can make models compose for readability and verifiability.



On the subject of reactive modeling, the book focuses on higher order

concurrency patterns like actors and futures. It uses the Akka framework

as the reference implementation and demonstrates how advanced

architectural patterns like event sourcing and CQRS can be put to great

use in implementing scalable models. It offers techniques that are

radically different from the standard RDBMS based applications that are

based on mutation of records. It also shares important patterns like using

asynchronous messaging for interaction based on non blocking

concurrency and model persistence, which delivers the speed of inmemory

processing along with suitable guarantees of reliability.
