For me Big Data is slightly different. The name refers to the larger quantity of data but larger than what? Basically, in my opinion, Big Data is the pooling of data from multiple, even numerous, sources. For some, Big Data amounts to a quantity of data that, for others, is of a smaller scale than before Big Data. So Big Data is more data, but only relative to ones own prior experience, that comes from a wider range of sources.

or

Big Data = Big Bucks!!! 😛
