Object-Oriented Programming (OOP) vs. Data-Oriented Programming (DOP) in Java

using Java record classes, sealed interfaces, and switch expressions to implement business logic outside of data classes,
the pitfalls of deep inheritance hierarchies and instance of checks,
modeling data with records and sealed interfaces,
validating data at the boundaries and ensuring immutability,
the advantages of data-oriented programming for maintainability and safety,
applying data-oriented programming to web services and data pipelines,
combining enums with records for complex configurations

The Abstract Factory pattern is there. Using runtime polymorphism it will decide.
