[VDBUH2023] - Nicolai Parlog - Data-Oriented Programming in Java (20)

In data-oriented programming (DOP), we model data as data and polymorphic behavior with pattern matching. This talk will introduce the concept of DOP and its four principles: model the data, the whole data, and nothing but the data data is immutable validate at the boundary make illegal states unrepresentable We’ll also explore how to use pattern matching as a safe, powerful, and maintainable mechanism for ad-hoc polymorphism on such data that lets us define operations without overloading the types with functionality. The talk ends with a juxtaposition to OOP, so you not only learn how to employ DOP but also when (not).
