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).

In the coming months, I'll present this talk at Accento @ JUG Karlsruhe and ElsassJUG. If you're there as well, I'd love to meet you - I'm always up for a chat. 😁 Just flag me down when you see me. (This includes chat rooms.)
