We first need to ask ourselves what Data is. Data is any kind of information available to us in form of numbers, words, pictorial representations etc.; information that we perceive and derive meaning from. In coding and software languages, data becomes the numerical values that we come across. As the name suggests, Big Data is the kind of data that is too big, sometimes so vast that it cannot be easily perceived. So how do we handle such big data available to us? We use Big Data Analytics. This technique is used to perceive large amounts of data to derive meaningful information from it.
For example, you are required to monitor the shopping habits of consumers. You develop a software that records how the consumer takes in the market and what drives them to choose an item over the other. This type of study is done on a large group, therefore the data available to you will be extensive to support your study. Big Data Analytics technique enables you to make sense of the data and conclude the results from it. Online consumer market giants like Amazon and Google use this technique to analyze your preferences and help you find the items best suited to you.
Is Big Data really that big?
Yes. With 7.8 billion people inhabiting the earth and engaging each day with each other either directly or indirectly, the data they produce in the process is bound to be big. Half of this number is on the internet, interacting with various sites. According to a report by Forbes, 2.4 quintillion bytes of data is produced each day. Facebook, the biggest social media site, saw 2.7 billion monthly active users in the second half of 2020, according to a Statista article.
What are the characteristics of Big Data?
There are 3Vs of Big Data that help companies grow in their domains.
Volume: Volume is the data that is generated. As we discussed earlier, there is an exponential growth of data every second in the world. Companies buy cloud storage to record this substantial data in order to analyze this at a later stage.
Velocity: Velocity is the speed at which the data is generated and received. This is the calculation of the speed at which the data flows on sites, such as application forms, social media sites, etc.
Variety: This refers to the sources, types, quality, and various other factors that distinguish the data. This can range from structured to non-structured data such as images, audios, gifs, transactions etc.
Why is Big Data Analytics important?
In today’s world where consumer is the focus of every industry, keeping track of behaviours and habits becomes important. Companies need to be up-to-date with information in order to cater to the mass. With over 1gb data produced every second, companies need to find a way to analyze it quicker and more efficiently. The technique enables the organisations to tap into newer business opportunities and keep themselves ahead in the game in this competitive world. This not only helps them to reduce cost and make decisions faster, but also gage the right products according to the demand, ensuring satisfaction at the consumer’s end. Also, there is a need to keep record of what is happening around the world and what minor or major events take place and when.
