Data-oriented design is a paradigm that boils down programming to transformations of data. Treating software in this way allows programmers to make better use of modern computing hardware, where transferring memory from RAM to the CPU cache is very slow and operating on large chunks of sequential data is very fast. Code also becomes simpler to write and follow, but it loses some reusability in the process.
