Among many articles, the most interesting article was <Society>. I did not know what big data is exactly, also I did not know it was used to figure out how MERS broke out. However, through the article, I now can define what big data is. Also, because the article handled both sides of advantage and disadvantage of big data, I could learn disadvantages of big data which I did not know. It was very useful article to me as I could learn new information.
