What BIG-DATA is
In simple words, we can define big data as a huge/massive amount or collection of data that can be nearly any-type, any-size and variety.
Big Data | Estimated Size
According to IBM:
“Around 2.5 quintillion bytes of data is created every day.”
Big Data | Types
There are generally 2 types of data that currently exist:

Structured Data
(Data that resides in a fixed field within a record or file is called structured data.)
Unstructured Data
(It is a type of data that includes text, audio, videos, photos, web pages, documents, email messages, word processing and so on.)
According to TCS:
“In the current world almost 51% of data is structured data. 27% data is unstructured data while the rest, 21%, is called semi-structured data.”
Big Data | Generated Jobs
According to GARTNER:
“There are as much as 4.4 million IT jobs that will be created globally to support big data by 2015. The technology will generate 1.9 million IT jobs in the USA alone and all the rest will be divided in the whole world.”
Big Data | Talent Required
According to McKinsey:
“The USA alone could face a talent shortage of around 140K – 190K people by 2018. Further this shortage can get exceeded. According to their estimation the shortage can reach up to 1.5 million; that will include managers, analysts and so on to make effective decisions on big data. ”
Big Data | Re-Planning
According to TEK Systems:
“Around 81% of IT leaders and 77% of IT professionals believe there is a considerable shortage of talent that could make best use of their organization's data assets.”
