Big Data examines what people say about what they have done or will do. That is in addition to tracking what people are actually doing about everything from crime to weather to shopping to brands. It is only Big Data is capacity for dealing with vast quantities of real-time unstructured data that makes this possible.
In a fast-paced and hyper-connected world where more and more data is being created, Hadoop’s breakthrough advantages mean that businesses and organizations can now find value in data that was considered useless.Organizations are realizing that categorizing and analyzing Big Data can help make major business predictions. Hadoop allows enterprises to store as much data, in whatever form, simply by adding more servers to a Hadoop cluster. Each new server adds more storage and processing power to the cluster. This makes data storage with Hadoop less expensive than earlier data storage methods.
