"Extreme performance data warehouse" refers to handling of “big data" or the processing of tera, peta, exa, zetta, yotta bytes of information and the ability to gleen information from these huge data sources. For those of you who are unfamiliar with these terms, tera is 10 to the power of 12 or 1000 to the power of 4 bytes (or 2 to the power of 40 bytes or 1024 to the power of 4), peta is 10 to the power of 15 or 1000 to the power of 5 bytes (or 2 to the power of 50 bytes or 1024 to the power of 5), exa is 10 to the power of 18 or 1000 to the power of 6 bytes (or 2 to the power of 60 bytes or 1024 to the power of 6), zetta is 10 to the power of 24 or 1000 to the power of 7 bytes (or 2 to the power of 70 bytes or 1024 to the power of 7) and yotta is 1000 to the power of 8 bytes!
In other words, If a MB (1,024,000 bytes) is a tablespoon of sand, then a gigabyte is patch of sand that is 9” square and 1’ deep, a terabyte is a sand box that is 24’ square and 1’ deep, petabyte is a mile long beach that is 100’ wide and 1’ deep, exabyte is the same dimension beach from Maine to North Carolina, zettabyte is the same beach covering the whole US coastline, and yottabyte is enough sand to bury the entire US in 295 feet of sand! For those who are curious, after yottabyte is brontobyte, then saganbyte and lastly pijabyte…
