I work with state labor data which is reported to us in the form
industry, year, quarter1, quarter2, quarter3, quarter4
where each quarter represents an employment count. Obviously, this can
be normalized to
industry, year, quarter, employment
Can anyone comment on, or point to me to an article or discussion
regarding, why one would use an array column instead of normalizing
the data? That is, would there be any benefit to storing it as
industry int, year smallint, employment int[ ]
where the last column would be a four element array with data for the
four quarters.
Thanks,
