In web applications it is common practice to use repository pattern for data access. Usually this is the way to extract data from a database. For example:

from sqlalchemy.orm import declarative_base


Base = declarative_base(...)

class User(Base):
    id: ...
    first_name: ...
    last_name: ...


class UserRepository(BaseRepository):
    def get_by_id(self, ...): pass
    def get_all(self, ...): pass
    # etc

But what if the source of data are external API or excel file? When working with API they usually call a repository as a “client”. But it gets data and the meaning is the same. Should I name the class SomeExternalAPIRepository? What about extracting data from Excel file? SomeExcelRepository?

What is naming convention for listed cases?
