Hi JOG,

You must've snipped my reference to one of many of Codd's papers on the subject. You liked his 1970 work, I thought you might've enjoyed some of his other contributions as well ;-)

Granted the simplicity of the earlier version of the model has great appeal, but surely you can admit there are limitations, If you haven't discovered any, nevermind, enjoy you day.
