Not what you had in mind?
It works, but I call this an example of the quip that when the only tool
you have is a RDBMS then all data look like tables.
In a multi-dimensional sparse array database your X and Y axes might be
latitude and longitude, your Z axis might be altitude, your T axis is
time. Temperature, humidity and pressure are some of the actual data at
a given intersection of these axes. Keep in mind that this is still
wholly structured data which makes it relatively easy to represent in
tabular form. Less-structured data won't fit so easily without resorting
to hacks like embedding whole JSON objects in table cells.
