What is Big Data?

What is Big data?
Every day, we create 2.5 quintillion bytes of data i.e voluminous amount of structured, semi-structured and unstructured data that has the potential to be mined for information. 90% of the data in the world today has been created in the last two years alone. This data comes from everywhere: sensors used to gather climate information, posts to social media sites, digital pictures and videos, purchase transaction records, and cell phone GPS signals to name a few. This data is big data, the term is often used when speaking about petabytes and exabytes of data.
