Data Scientist and big data



what do you mean by Data science and Big Data as job roles, are they same ? and how Data science is different by Business analytics.

As data science is a very common word on this site , so I am really curios to know its definition, and if it is different from the term business analytics or a part of it.

Same for the term BIg data.


Hi Avnish,

Big data is normally used in the place where you need to “manage” huge volume, variety and the velocity of the data.

Data science refers to the techniques that you apply upon the data to bring our the hidden insights or simply put the study of the hidden patterns in the huge data available.
