Can you please explain what is the difference between "Member fields" and "Data fields" in this context?

I ask because they are about the same in my opinion

The term "Member fields" is more from Java language perspective because such fields are members of a class. While the term "data fields" is more from data perspective as they hold business data.
Of course, in Java, all data fields will be members of a class. But all member fields may not necessarily be used to keep data.

Thanks a lot
