Big data is … big data.
Big data is not that extra large data volumes. big data is primarily an alternative to traditional databases. This data can be structured or unstructured .
Everything we do produces big data : the sites where we surf or connected TV , it’s everywhere.
What is it used primarily ?
To know us better , to offer products and services closer to our interests.
There are a lot of articles on this topic and even videos … In conclusion, I would say big datas are the ears and eyes of Internet (in its way).
