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.
