Definition of big data

Collectively, the volume of data being generated has come to be termed big data and analytics that include a wide range of faculties from basic data mining to advanced machine learning is known as big data analytics. There isn't, as such, an exact definition due to the relative nature of quantifying what can be large enough to meet the criterion to classify any specific use case as big data analytics. Rather, in a generic sense, performing analysis on large-scale datasets, in the order of tens or hundreds of gigabytes to petabytes, can be termed big data analytics. This can be as simple as finding the number of rows in a large dataset to applying a machine learning algorithm on it.
