Data-oriented design takes its cues from the data which is seen or expected. Instead of planning for all eventualities, or planning to make things adaptable, there is a preference for using the most probable input to direct the choice of algorithm. Instead of planning to be extendable, it plans to be simple and replaceable, and get the job done. Extendable can be added later, with the safety net of unit tests to ensure it remains working as it did while it was simple. Luckily, there is a way to make your data layout extendable without requiring much thought, by utilising techniques developed many years ago for working with databases. — Data-Oriented Design
