What is big data?
Big data is data sets that are very big and complex.
As information and communication technology develops, the amount of data we have is getting much greater than before.

Big data has to be analyzed, and this is done by big data experts.
Using various methods, experts analyze big data and draw meaningful results from it.
These results then can be used to make decisions or to predict the future.
How is big data influencing our lives?
Big data is influencing almost all parts of our lives.
