In this high-tech and modernized world, an essential asset is data. It is a simple four-letter word, but the power it holds is enormous. At a time when smartphones and technology are essential to every human being, 1.7 megabytes of data is generated every second! At this rate, IDC researchers estimate that the global data will grow to a whopping 175 zettabytes! 

The essential thing to understand is that big data is useless until it is sorted and fundamental information is mined out from the massive volumes of data. It is necessary to discover a way to interpret, structure, and present the data in a meaningful and fruitful way. 

This is where the skillset and power of data scientists come in to help businesses and start-ups. A data scientist harnesses big data to find and analyze trends, apply analytics, and discover features and insights to enhance business strategies.

As per experts in the US Bureau of Labor Statistics, the demand for data scientists is expected to rise by 15% by 2029, and the jobs related to data science are supposed to increase by 26% by 2026.

However, what does a data scientist do that makes them highly regarded by the blooming and giant companies? 

How has Data Science evolved?

Forbes’ article titled “A Very Short History Of Data Science”, along with other resources cites that a mathematician named John Tukey was the first to suggest the upcoming field of data science, which focused on gathering insights or learning from data. He wrote and explained the convergence of statistics and computers to calculate measurable outputs within hours. 

In 1974, Peter Naur, a Danish computer science pioneer, used the term “Data Science” frequently throughout his book called “Concise Survey of Computer Methods.” 

When the entire world got universal access to the Internet, and smooth connectivity, along with it came, it opened the gateway to storing data collection. In 2005, traditional technologies could not store and manage massive data collected by Facebook and Google, and the need for new and efficient technology rose. Hadoop, Cassandra, and Spark made their debut and saved the world by handling Big Data. 

By 2013, when IBM revealed that 90% of the global data had been created in the past few years, it was this time the world understood the importance of data science and its power to change business strategies. In 2015, Machine learning, deep learning, and artificial intelligence entered the realm of data science to make our lives easier by bringing AI into our lives. 

In the 2020s, there are breakthrough technological innovations with the help of data science and artificial intelligence. Cloud computing transformed the way an organization approaches information technology. Cloud-based technologies opened the way for the Internet of Things and data science to monitor and collect data in real-time. 

Data scientists are trying to find ways to develop intelligent and autonomous AI through machine learning. They are using deep learning to make smart computers, which will help create powerful and advanced robots with intelligent AI. If you imagined a world of robots and humans interacting with each other seamlessly, hold on to that thought because it might soon become a reality. It will help automate labor, and the health, transportation, finance, and defense industry will witness a revolution. 

Prominent use cases for Data Science in 2023

Data Science can be defined as the process of building, cleaning, and structuring datasets for analyzing and finding a pattern or information from the data stack.

What is Data Science used for?

Have you wondered how data science works? Here are four prominent ways data scientists use to study and analyze the data:

Descriptive Analysis

By examining the data, descriptive analysis helps to find what happened in the past or what is happening currently. The best example where descriptive analysis can be used is to record the number of tickets booked using a flight booking service.

Diagnostic Analysis

Diagnostic Analysis is the detailed examination to understand the reasons that led to the present situation. Diagnostic Analysis is used by the same booking service to find out what caused a booking spike in the previous month. 

Predictive Analysis 

Predictive analysis uses data to make precise and accurate forecasts of what may happen in the future. For example, the flight booking service may use predictive analysis to understand and predict ticket sales for the next year.   

Prescriptive Analysis

Prescriptive analysis is the next and upgraded version of predictive analysis. It helps to predict all the possible outcomes of the decision. Apart from predicting the future, it also suggests the best course of action to deal with the outcome. 

How is Data Science helpful for the Business and IT Industry? 

Here is how data science helps numerous start-ups, businesses, and IT industries to grow and expand impeccably: 

  1. Data Science helps to unravel unknown and hidden transformative patterns that have the potential to increase user engagement and profit margins. 
  2. The insights and conclusions drawn by examining the data can help businesses to innovate and enhance their services and products. 
  3. Data Science helps to find an effective solution for problems commonly faced by companies that can bear heavy losses. It helps large-scale companies to respond promptly to changing conditions and optimize their business strategies to maintain the profit margin. 
  4. It also helps organizations and businesses make essential decisions for the betterment of the business, backed by numbers and figures.

4 Key skills in Data Science   

Data science is a combination of computer science, data technology, visualization, mathematics, and statistics. However, only a technical skill set cannot define whether a particular candidate can contribute to the success of the company business. Non-technical skills play a significant role, just like technical skills. 

Data scientists having a Master’s or Ph.D. in statistics, mathematics, or computer engineering are best suited for this job. Here are technical skills that a data scientist should have expertise at: 

1. Programming
