Please show Neo is a fraud by using Hugo's solutions to represent the following without NULLs or redundant data.

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 show Neo is a fraud by using Hugo's RM Sol#1 or #2 to generate the Small Report in not more than twice the time it takes XDb1 on the same system. As shown by the measurements made below, even when executed on a 5.6 times slower 233 Mhz Pocket PC, XDb1 generated the small common ancestor report nearly twice as fast as Hugo's non-normalized, non-generic SQL Server 2000 Solution running on a 1,300 MHz desktop. Please run XDb1 and Hugo's RM#2 solution on your system and post the measurements exposing Neo as a fraud.
