Unser nächster Vortrag von **Nicolai Parlog** dreht sich um das Thema **Data Oriented Programming**. Die Firma **LivePerson** heißt uns freundlicherweise in ihren Räumlichkeiten in den **Mannheimer Quadraten** willkommen.

**Abstract**
Data-oriented programming models data as data: records for entities and sealed types for alternatives. Combined with pattern matching we can define operations on the data without overloading it with functionality.

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).

**Bio**
Nicolai (aka nipafx) is a Java enthusiast focused on language features and core APIs with a passion for learning and sharing – in articles, newsletters, and books; in tweets, videos, and streams; in demo repos and at conferences – more on all of that on nipafx.dev. He’s a Java Developer Advocate at Oracle and organizer of Accento. That aside, he’s best known for his haircut.
