With the advent of increasing digital technology companies have to collect huge amount of data. It is difficult to manage such huge amounts of data with normal analytical tools. This has given rise to some stronger analytical tools which are capable of making sense out of this pile of data. It has resulted in the birth of big data analytics, which has emerged as a necessary tool requiring specialized skills.
Big Data is getting more popular by the second. Its annual Growth rate is predicted to be US$ 32.4 billion in 2017.
