  The continuous increase of data generated provides enormous possibilities of
both public and private companies. The management of this mass of data or big
data will play a crucial role in the society of the future, as it finds
applications in different fields. There are so much potential and extremely
useful insights hidden in the huge volume of data. The advanced analysis
techniques available including predictive analytics, text mining, semantic
analysis are needed to enable organizations to create a competitive advantage
through data analyzed with different levels of sophistication, speed and
accuracy previously unavailable. Therefore, is it still possible to have that
level of sophistication with the ubiquitous numeric ocean that accompanies use
every day via connected devices that invade our lives? However, development of
big data requires a good understanding of the issues associated with it. And
this is the purpose of this paper, which focuses on giving a close-up view of
big data analysis, opportunities and challenges.
