Big Data Definition


What is Big Data ?

Big Data can be defined as a large amount of structured and unstructured data that is meant to be mined for information.

Big Data is a generic term refering to very large volumes of data that companies have to deal with. The arrival of these large data has become a real challenge for companies whose current systems were not designed for such massive treatments.

Today the production of data has never been more important. Every day, human activities generate data on a volume of over 2.5 trillion bytes, or more than 2.5 trillion data.

The exponential growth of data is unprecedented in our societies: the development of e-commerce, the generalization of digital marketing, the proliferation of connected devices and sensors, social networks on the Internet, images and videos posted online, geolocation are among the new practices that contribute to this growth. The growth is such that today 90% of the data generated were only in the last two years, and this proportion continues to grow.


The challenge brought about by these massive data is not only linked to large volumes of data but also to their diversity: in organizations, the traditional structured data must now cohabit with unstructured data of unconventional formats. The challenge is to make sense from these massive amounts of data. Companies have to master these massive data, analyzing them to better understand them so that they represent a real meaning and value.
