Key Difference Between Big Data vs Data Mining. Big Data and Data Mining are two different concepts, Big data is a term which refers to a large amount of datawhereas data mining refers to deep drive into the data to extract the key
I would say that Data Mining is data analysis unrelated to data quantity. Big Data is just a qualitative adjective that means a heavy amount of data. Terms are unrelated.
In common practice, Big Data term implicitly implies further analysis on itself.
