Re: Oracle and PICK
The point is, IMO, that you can project a three dimensional relation (or,
maybe a third order relation) onto a two dimensional space (rows, columns)
If it weren't for the capacity of two dimensional tables to capture and
retrieve data that might be three dimensional or beyond, a star schema
would be impossible.
In other words, the table has only two dimensions, but the relation is of
order 3, and therefore can list a (finite) set of points in a three
Mathematical relations are not limited to finite cardinality, but I'm
putting that limitation on the relations in the relational data model. Now
that I think of it, is this a legitimate limitiation or not? Your
Clear as mud?
