What is Big Data? You may ask; and more importantly why it is the latest trend in nearly every business domain? Is it just a hype or its here to stay? As a matter of fact “Big Data” is a pretty straightforward term — its just what its says — a very large data-set. How large? The exact answer is “as large as you can imagine”!
How can this data-set be so massively big? Because the data may come from everywhere and in enormous rates: RFID sensors that gather traffic data, sensors used to gather weather information, GPRS packets from cell phones, posts to social media sites, digital pictures and videos, online purchase transaction records, you name it! Big Data is an enormous data-set that may contain information from every possible source that produces data that we are interested in.
Nevertheless Big Data is more than simply a matter of size; it is an opportunity to find insights in new and emerging types of data and content, to make businesses more agile, and to answer questions that were previously considered beyond our reach.
