Evolution of Big Data Analytics

The evolution of big data analytics can be traced back to the early days of computing when organizations first started to realize the potential of using large data sets to find hidden patterns and trends. 

One of the earliest examples of this was in the 1960s when the US government used big data to track the movements of Soviet submarines. Since then, big data analytics has come a long way. 

With the advent of powerful computers and sophisticated software, it’s now possible to process and analyze large data sets much more quickly and easily. 

When we talk about the history of big data analytics, we have to start with the term ‘big data itself. John Mashey first coined the term in 2001, and it referred to data sets that were too large and complex to be dealt with using traditional data processing methods. But it was in 2005 that the term started to gain traction when a group of scientists from Google published a paper on a new way of dealing with big data sets. They called it ‘MapReduce’, and it was a game-changer. Since then, there have been a number of other advances in big data analytics, including the development of new storage technologies, new ways of analyzing data, and new applications for big data. 

This has led to a surge in the use of big data analytics, and it’s now being used by businesses and organizations all over the world to find hidden insights that can help them make better decisions. 

Today, big data analytics is used in various industries, from retail to healthcare to finance. And it’s only going to become more critical in the years to come. 

What is big data analytics? 

Big data analytics is the process of examining large data sets to uncover hidden patterns and insights. This can be done manually, but more often than not, it’s done through the use of specialized software and hardware tools. 

A big data analyst is someone who is responsible for analyzing large data sets to uncover hidden patterns, correlations, and other insights. They look for trends and patterns and then develop hypotheses about what those trends mean. From there, they develop plans to act on those findings. 

This is a critical role in any organization, as big data is only becoming more and more important. This process of turning large data sets into actionable insights is quickly becoming one of the most important tools for businesses of all sizes. The insights gleaned from big data analytics can help businesses make better decisions about everything from product development to marketing to customer service.

Use of Big Data with a Use Case: 

The word Big Data refers to structured, semi-structured, and unstructured data, which is huge in Volume, Velocity, and Variety. 

Let us look into this in detail with an example: 

Let’s say, for example, user A is browning a website X for a shirt. Unfortunately, the shirt the user A is searching for is out of stock. However, website X shows similar shirts based on his search; hence user A ends up buying two to three shirts now instead of one. The website X will again send a mail to user A once the shirt he was initially looking for is back in stock. Here the goal of more sales and happy customers is fulfilled, but how exactly did this happen? 

Over time, website X collects lots of data (Volume) about many customers like Users A.Similarly, the data is collected in the food, games, social media engagement, etc ( Variety). Hence website X collects data at different rates ( Velocity ). Some over a period a time and few Being live data. The algorithms that can analyze the customer’s behavior are used in this aspect hence making the best use of the data. With this, the following can be achieved: 

• The customer’s needs will be fulfilled without extensive search (in our case, shirt)
• Greater Revenue by showing and recommending what customer wants
• Continuous learning by the system, through which the system suggestions can be completely accurate in the future that might match the customer’s likes and wants 

Hence in this way, Big Data Analytics can be used to : 

• Get actionable insights. 
• Uncover hidden patterns. 
• Find correlations in data. 

This helps businesses to cut costs, increase their revenue with minimal manual intervention, improve business productivity and create much more intelligent organizations.
