In computing, data-oriented design is a program optimization approach motivated by efficient usage of the CPU cache, 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. 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.
