Please use RM Sol#1 or #2 to create the hierarchal reports for the following without NULLs or redundancy:
Case1: God is the parent of an unnamed person. God is also the parent of second person with three names (string 'john', integer 100, decimal 3.14).
Case2: john isa person. john's color is brown. mary isa person. mary's color is brown. brown is a person.
Please respond in original thread. Below are measurements made thus far using RM solutions that aren't as generic or normalized as XDb1's.
