What is Big Data?
Gone are the days when people were happy about getting a laptop with 40 GB of data storage. 40GB was ‘much‘ at that time. Fast forward to today, we generate around 2.5 quintillion bytes of data each day and the number grows with every passing day. Now, the present-day data cannot be handled by old databases. This is where the term Big Data comes into the picture; it refers to the data that is too huge and complex to be stored in traditional databases. Companies want this big data to be processed, stored, and analyzed so as to draw meaningful inferences from it and make informed business decisions.
