Eliminate the unavoidable complexity of object-oriented designs. Using the persistent data structures built into most modern programming languages, Data-oriented programming cleanly separates code and data, which simplifies state management and eases concurrency. Data-Oriented Programming teaches you to design applications using the data-oriented paradigm. These powerful new ideas are presented through conversations, code snippets, diagrams, and even songs to help you quickly grok what’s great about DOP. You’ll learn to write DOP code that can be implemented in languages like JavaScript, Ruby, Python, Clojure and also in traditional OO languages like Java or C#.

2. Data-oriented programming is an exciting new paradigm that puts data at
the heart of your code. The result is faster applications, and a clearer and
more flexible code base. This is achieved by adhering to the 3 core
principles of Data-oriented programming:
1. DOP separates code from data instead of combining them into objects
and classes.
2. Data is manipulated with generic functions and treated as a first-class
citizen.
3. Data is immutable.

3. Data-Oriented Programming teaches you to implement the data-oriented
paradigm in traditional object-oriented languages like Java, C# or
JavaScript. Powerful new ideas are presented through conversations,
code snippets, diagrams, and even songs to help you quickly grok what’s
great about DOP.
No more complicated UML diagrams. Welcome simplicity.

4. Data-Oriented Programming is a hands-on guide to the design and
implementation of data-oriented systems.
Throughout the book, you’ll build a production-ready library management
system using the DOP paradigm.
You’ll learn to:
1. Represent business entities with data
2. Manipulate immutable data collections with ease
3. Build highly scalable concurrent systems
4. Write unit tests for data-oriented systems

This is a great
guide to using
Data-Oriented
Programming to
improve any new
or existing OOP
codebase.
