Data-Oriented Programming: Reduce software complexity

Eliminate the unavoidable complexity of object-oriented designs. The innovative data-oriented programming paradigm makes your systems less complex by making it simpler to access and manipulate data.

In Data-Oriented Programming you will learn how to:
• Separate code from data
• Represent data with generic data structures
• Manipulate data with general-purpose functions
• Manage state without mutating data
• Control concurrency in highly scalable systems
• Write data-oriented unit tests
• Specify the shape of your data
• Benefit from polymorphism without objects
• Debug programs without a debugger

Data-Oriented Programming is a one-of-a-kind guide that introduces the data-oriented paradigm. This groundbreaking approach represents data with generic immutable data structures. It simplifies state management, eases concurrency, and does away with the common problems you'll find in object-oriented code. The book presents powerful new ideas through conversations, code snippets, and diagrams that help you quickly grok what's great about DOP. Best of all, the paradigm is language-agnostic—you'll learn to write DOP code that can be implemented in jаvascript, Ruby, Python, Clojure, and also in traditional OO languages like Java or C#.

About the technology
Code that combines behavior and data, as is common in object-oriented designs, can introduce almost unmanageable complexity for state management. The Data-oriented programming (DOP) paradigm simplifies state management by holding application data in immutable generic data structures and then performing calculations using non-mutating general-purpose functions. Your applications are free of state-related bugs and your code is easier to understand and maintain.

About the book
Data-Oriented Programming teaches you to design software using the groundbreaking data-oriented paradigm. You'll put DOP into action to design data models for business entities and implement a library management system that manages state without data mutation. The numerous diagrams, intuitive mind maps, and a unique conversational approach all help you get your head around these exciting new ideas. Every chapter has a lightbulb moment that will change the way you think about programming.
