> To me this sounds very much like functional programming as well despite the fact that in OP's link it is said that >> Distinguish data-oriented programming from functional and OO programming Yes, that was the basis of my question. The book description also states: > In DOP, you maintain application data in persistent generic data structures separated from the program’s code. You use general-purpose functions to manipulate the data without mutating it. Which seems a lot like functional programming. The use of 'persistent' is perhaps interesting, though there's nothing inherent in FP that excludes persistence obviously.
