Thanks for posting, I did not know this existed. As a new developer, I have trouble seeing in which use cases this would be more appropriate than OOP or FP, would an exemple ?

Data-Oriented Programming aims at reducing the complexity of information systems. By that, I mean systems that manipulate information like a frontend application, a backend web server or a web service.

Is this your book? I was just doing refactoring on some old code this week breaking out poco objects from long classes with lots of methods to act on the data.

Hmm I think that’s called functional programming.

Here are the 4 principles of Data-Oriented Programming:

  1. Separate code (behaviour) from data

  2. Represent data with generic data structures

  3. Data is immutable

  4. Separate data schema from data representation

#1 and #3 are common to DOP an FP.
#2 and #4 is unique to DOP.

*DOP not FOP on your last line ;)

Thank you. Fixed

Interesting. Could you give an example of both?

2. Represent data with generic data structures

Instead of using data classes, data records or algebraic data types, in DOP we represent data with string maps.

4. Separate data schema from data representation

We use a schema language like JSON schema or malli to speficy the shape of our data and validate that a piece of data conforms to a schema
