Big Data is Big News. Big consultancies and senior managers are all using the term "Big Data" these days. The words are the "Information Superhighway" of this decade*. Over-used, over-hyped and mis-understood.
In practice I tend to refer as something as "Big Data" if I can't inset it & work with it in an Excel spreadsheet... even though we've has databases for half a century that can deal with more than 1,048,576 rows (which is actually the maximum rows you can get in an Excel spreadsheet).
However there can be a lot of insight that can be gleaned from much smaller data sources. You don't need to have access to every single customer record in a database to analyse most trends about your users. You only need to examine a smaller accurate and representative data set. It can't be incomplete, out of date or incorrect.
So shouldn't we really use the term "Better Data"?
*BTW: What is this decade actually called? Sure we had "the Eighties", "the nineties" and even the "noughties"... but are these "the teenies"?
