>>I'm curious how many people here use SET RELATION data relationships for viewing parent/child local data, as compared to SQL queries / views which load everything into a single file? I've observed that most old school developers (began in the 80s) use SET RELATION, and most newer developers prefer SQL almost exclusively (and I think many would prefer LINQ).

Haven't used set relation in a long time. I do often use lookup() to get descriptions from code fields to cut down on the SQL.
