Because persons make the same type of comments or ask the same question over and over again and the answer is still the same.

If persons are't bored by making the same type of comments or asking the same question over and over again, then perhaps they aren't bored by getting the same answer over and over again.

Thanks for your comment. Perhaps, but why not convince the last remaining few people that Neo is a charlatan, by using 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, please post your solution/report in original thread.
Below are measurements made thus far using RM solutions that aren't as generic or normalized as XDb1's.
