The Big Data Revolution

Big data describes a large volume of data both structured and unstructured which helps a business to move on a day-to-day basis. Gathering the data is not important, but what the organizations do with the data that matters most. Big data is analyzed for problem-solving that leads to better decisions and strategical business moves.
Big data surrounds around the large sets of information that grow at increasing rates. It covers the volume of information, the velocity or speed at which it is created and collected at a steady or viable rate, and the variety or scope of the data points being covered. Big data often comes from various sources and arrives in multiple formats. The definition of big data is divided into three V's:

Volume: Organizations collect data from a variety of sources, including transactions, smart devices, industrial equipment and more. In the past, storing was a problem, but cheaper storage on platforms like lakes and Hadoop have eased the burden of cost.
Velocity: With the growth in the IoT, data streams into businesses at an unmatched speed and must be handled in a timely fashion. sensors and smart meters are driving the need to deal with these events of data in near-real-time.
Variety: Different type of data format in today’s world are – from structured data, numeric data in traditional databases to unstructured text i.e. documents, emails, videos, audios, stock data, and financial transactions.

The term ‘Big Data’ has been coined since the early 1990s.
Big Data has been picking up the pace over the decade. Over the course of centuries and as time rolled by, we have been trying to use data analysis techniques to ease their decision-making process. The ancient Egyptians around 300 BC already tried to capture all existing ‘data’ i.e. information in the library of Alexandria. Moreover, the Roman Empire used to carefully analyze statistics of their military to determine the optimal distribution for their armies in the battlefield to get an upper hand.
However, in the last two decades, the volume and speed with which data is generated and changed the world has changed beyond measures of human thinking. Even with the most advanced technologies today, it is impossible to analyze all this data within human reach. Big data has brought a revolutionary change in the new world.

Why is Big data important?
Answering important customer questions.
  • What customers want in a day to day basis
  • Where they’re missing out on daily conversions
  • Who their best customers are 
  • Why people choose different products keeping their products aside
  • Every day, companies gather more useful insights into their sales and marketing questions, so they can begin to adjust their client’s campaigns. The more they learn about their customers, the more competitive company becomes. 

Optimising & Understanding Business Process

Big data technologies like cloud computing and machine learning help’s us to stay ahead of the curve by identifying inefficiencies and opportunities in company practices. 
For instance, big data analytics can tell us that how our email marketing strategy is working, and social media profiles aren’t reaching to the right people. On the other hand, if  using big data internally, we can find out which parts of your company culture are having the right impact, and which maybe causing a turnover.

Giving us a detailed analysis
Big data-based applications help’s big data analysts, data scientists, predictive modelers, statisticians and other analytics professionals to analyze growing volumes of structured transaction data.

Big data in today’s world

Most organizations use big data for their business. They understand the need to utilize the data and extract values from it.
  • Machine Learning: the concept is applied to huge quantities of data.
  • Health Care & Big Data: big data has a lot of scopes and no other than healthcare can take advantage of it.

In the end, one can say that industries are on fire with the data eruption. No sectors have remained untouched from the technology. It has deepened inside each business and become an essential part of business operations.
