This surge in data has shaken us out of our personal silos and grouped us all as part of one big collection- Homo sapiens, the makers as well as users of data.





What is Big Data?

Who are Big Data Analysts?
Any data is futile without the proficiency and the expertise to analyze it. The major question here is not how much data each business has access to, but what use they put this data to. Hence, arise the need for trained Big Data Analysts or Data Analysts- people who can analyze or assess data volumes to deduce pattern, do calculations and use statistical, technical and analytic expertise to help businesses make real, factual and data backed decisions and formulate business strategies.
