That makes no sense. A table models a set of things of one kind; each
rows is one instance of that kind of thing; each column models an
attribute by storing scalar values. This nightmare is a blob of ~20
different things!! What would the name of this thing be in a logical
data model? -- something along the lines of
"Bagpipes_Automobiles_SuperModels_ .._Alligators" for ~20 nouns where
the undescore can be read as "or maybe" ??
attributes into several, ~20, disjoint sets where the elements of each
set occur together. <<
