  • I don't like the label big data", because that suggests the key measure is how many bits you have available to use. But who cares how much data you have? With too little data, you won't be able to make any conclusions that you trust. With loads of data you will find relationships that aren't real. ... Big data isn't about bits, it's about talent." This is a quote by ZestFinance.com CEO and former Google VP of Engineering Douglas Merrill (1970 -). The quote appeared in his May 1, 2012 blog at Forbes.com.
