Please help Neo owe Hugo $1000 by using RM Sol#1 or #2 to create the
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).
Please respond in original thread. Below are measurements made thus far using RM solutions that aren't as generic or normalized as XDb1's. Note that XDb1's solution for generating a small common ancestor report running on a 233 Mhz Pocket PC is nearly twice as fast as that of a non-normalized, non-generic Sql Server 2000 solution running on a 5.6 times faster 1,300 MHz desktop.
