Data Scientists are also responsible for transforming their findings into presentations or reports which can be easily understood by clients or general audiences. Data Science, on the other hand, focuses on analysing the data and extracting useful insights for a particular individual, business, or industry. The easiest way to see if specific data can be labelled as Big Data is to analyse the 5 Vs (Volume, Velocity, Variety, Veracity, and Value). Big Data focuses on all the information which cannot be processed using traditional database systems. But the purpose and tools used by each discipline are different.
Master's degrees in Data Science & Big Data often overlap and teach students how to work with large amounts of information.
