In the article, it tells that big data is a huge size of data, used to describe a collection of data that is huge in volume and yet growing exponentially with time. Besides, volume, variety, velocity and variability are few characteristics of big data. It’s a convenient tool in our daily life to help us analyze the complicate or some massive data. Nowadays, there are many data or information on the internet, it helps to sort out and analyze the accurate data for us. It works on the principle that the more you know about anything or any situation, the more reliably you can gain new insights and make predictions about what will happen in the future. For example, we had made the NBA prediction during the class. We had downloaded some data of NBA, with those big amount of data, there are many useful database that we need it, however, there are also some meaningless that we didn’t need. Therefore, we need to go to SAS to analyze what we want to know. After the operating, we can get the data that we need. Beside, big data can not only do the prediction, it can also improve the healthcare, prevent the crime and improved customer service and make the better decision. Big data is changing our world and the way we live at an unprecedented rate. If Big Data is capable of all this today – just imagine what it will be capable of tomorrow. The amount of data available to us is only going to increase, and analytics technology will become more advanced.
