CONCEPTUAL CLARITY REQUIRED

[Sherlock Holmes]

I am returning to an old point of discussion , in the Shopping Bills dataset the Items category was of type List . Each item was a record of its own with fields like qty, price, cost etc . it was a list of records . So similarly in the Scores dataset ,  the Marks should be of list datatype ,i.e a list of records with each record having two fields Subject Name and Subject  Marks . Right?

That was my first clarification .

Second, 

 The fields Subject Marks  and Subject Name are individually of List data type , as they contain the list of marks of different subjects of a particular student . 

Third,

Can a list have only one entity and still be called a list?

PLEASE CORRECT ME WHERE I HAVE GONE WRONG IN MY UNDERSTANDING AS IT WOULD HELP US ALL HAVE A CLEAR CONCEPT .

[Sherlock Holmes]

ITS A REQUEST TO THE TEAM , TO KINDLY HELP ME OUT WITH THIS CONCEPT CLARIFICATION....

i dont get what your first doubt is. But for your second one,YES you can have list with only one element or even with no element at all.(Think of list as a set)

[Sherlock Holmes]

THE FIRST  AND SECOND ONE WAS NOT A DOUBT, I WAS JUST ASKING IF I AM VISUALIZING THE CONCEPT IN THE RIGHT WAY. I

DO YOU THINK ITS CORRECT? THANK YOU FOR CLARIFYING THE LAST DOUBT.

COULD THE TEAM PLEASE HELP ME?
