See LR about File VIEWS, this describes an Inner JOIN.
E.g., An order system has Customers and Orders.
Without Inner join, Visiting all customers, would return all Customers,
having Orders or NOT.
WITH inner join, Visiting all customers, would return only Customers that do
have Orders.
Resume:
1) it needs a relationship (JOIN)
2) it saves a lot of coding.
3) it does not work on a single-file.
