How big is big data?
It’s hard to fathom the enormous size of data we are working with here, so let’s start with a comparison. More data is produced every two days in 2012 than was produced entirely before 2003. In 2010, people generated 745 Exabytes of data. For those who have never heard of an Exabyte (cause I had to look it up) here you go: Exa, Peta, Tera, Giga, Mega, Kilo, byte—each being 1,024 times bigger than the previous. That is roughly 860,000,000,000,000,000,000 bytes, not to forget that a byte is 8 bits. These 860 billion-trillion bytes of data in 2010 will be significantly less than what is produced in 2011 and again in 2012.
Needless to repeat, that is Big Data. We must remember, though, that Big Data is more than just large amounts of data. Big Data is:
