In the early 1990s I did database consulting for a medical research support unit. They used Rbase for surgical results and survival analyses (S-Plus). Because no one there knew how to design a database all the data were in a single table; a flat file. When I re-wrote the database in Paradox/DOS as relational tables a number of duplicate rows were revealed. Having used duplicate data in the statistical analyses produced incorrect results that were published in medical journals. I was fired. :-) Rich _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
