Living with Big Data
Have you ever visited an online bookstore and been surprised by the books that
the store recommended for you? Many of them looked interesting to you.
So how did the bookstore know what you liked? This is all possible because of big data.
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. This is mainly because almost everything that we do online leaves a trace. For example, the photos you upload on your blog and the records of your purchases at online stores are
all part of big data.
Simply collecting data, however, is not enough. 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.
Improving Performance in Sports
Are you a sports fan? Well, big data is improving the performance of players, making sports more exciting. A famous example is Germany’s national soccer team. The team built a database by collecting and analyzing a huge amount of data on players. For example, the data included information about how much each player ran and how long he had
the ball. With the help of this database, Germany’s national soccer team was able to improve its performance and win
the 2014 World Cup.
Crime Prevention
Thanks to big data, police can now predict crime before it happens. Through the analysis of big data about the type,
time and place of crime, police can make a map of crime hot spots. This map identifies when and where crime is most
likely to happen. Police can prevent further crime by focusing on the areas and the times this map predicts.
Big data has already changed the world greatly. So where will the big data industry go from here?
Nobody knows for sure, but experts agree that big data will play a more and more important role in our lives.
