Then I probably misunderstood. If someone would like to post the SQL
script to model the data shown in
www.dbfordummies.com/example/ex012.asp , I think I could demonstrate
that swampish data structures (aka networks/graphs) are easier to
"navigate" with dbd's queries than with RM.

I don't think this schema can hold the data in the above example, but if someone could post the script to do so, I would like to see it. In particular, note that persons can be located in a building, on a floor of a building, in a room of a floor of building, etc. Received on Fri Jun 23 2006 - 21:24:03 CEST
