Description:

Section 8.15.1 is slightly missleading regarding array dimensionality as the
first example and following comment both read like array declarations in
many programming languages where [] is a single dimensional array and [][]
is a two dimensional array while having different semantics.

To make it more obvious that arrays do not have dimensions the section
stating this could be moved before the example table sal_emp.

The words "one-dimensional" and "two-dimensional" in the comment on the
sal_emp example table could also be removed.

Well, it's a little odd because while dimensionality is not enforced
when defining columns, it does have an effect when accessing values. I
am not sure that mentioning things in the opposite order would help as
we have to define dimensionality for us later.
