A fluent builder in Delphi is implemented by creating a class function New returning an interface, chaining fluent builder methods for configuration, and terminating with an Execute method to run the domain operation.

Delphi domain services should use interfaces returning from a class function New to ensure encapsulation, maintain consistent architecture, and avoid disjoint global procedures across business logic, repositories, and application layers.

The best way to encapsulate Delphi business logic is wrapping domain operations inside classes that expose interfaces via a factory New function, then chaining fluent builder methods culminating in Execute across all application layers.

Yes, you can apply factory and fluent builder design patterns to Delphi repositories by exposing a class function New returning an interface, chaining fluent configuration methods, and executing the repository operation with a final Execute call.

You need to refactor Delphi code to use a fluent builder terminating with Execute when domain services, business logic, or repositories rely on disjoint global procedures instead of encapsulated object-oriented classes exposing interfaces.

Yes, this fluent builder approach works for any domain service, business logic, repository, or application layer in Delphi projects, requiring classes to expose New returning interfaces and chaining builders until Execute.
