Data-oriented design

In computing, data-oriented design is a program optimization approach motivated by efficient usage of the CPU cache, often used in video game development. The approach is to focus on the data layout, separating and sorting fields according to when they are needed, and to think about transformations of data. Proponents include Mike Acton, Scott Meyers, and Jonathan Blow.

Not to be confused with Data-driven programming.

The parallel array (or structure of arrays) is the main example of data-oriented design. It is contrasted with the array of structures typical of object-oriented designs.

The definition of data-oriented design as a programming paradigm can be seen as contentious as many believe that it can be used side by side with another paradigm, but due to the emphasis on data layout, it is also incompatible with most other paradigms.
