What is Data Science and Why is it Important?

Data Science

One of the most well-liked growing fields and career opportunities is data science. According to a survey by LinkedIn, it has experienced a staggering 37% hiring surge over the previous three years, dominating its rising job ranking. Nearly every business is being revolutionized by data science, which is rising in popularity daily. However, what exactly is data science and why is it so crucial? You can find the answer to these questions in this post.

What is Data Science?

Understanding the data that is being discussed here is crucial to understanding data science. Any information about anything in the world that has been recorded is referred to as data. Simply put, data is anything in the world that has been recorded.

It may take the shape of written information, pictures, sounds, films, or other types of multimedia. The format of this data may be semistructured, unstructured, or structured. According to estimates, the world will have produced 79 zettabytes of data by 2021, and that number is likely to double by 2025.

What should we do with this much information? How can it be used to everyone’s advantage? What are the data’s practical applications? Data science provides answers to these questions.

It has been developing quickly and has essentially revolutionized many different businesses. Consequently, it becomes a little challenging to sum it up in a single formal term. It is a very broad field that keeps growing as big data keeps expanding exponentially over time.

However, in general, data science is the process of gathering clean, relevant information from dispersed and unstructured massive data in order to derive insights that can be put into practice.

How is any of this important, you may still be asking. Why is data science getting so much attention? You may not understand the critical importance of it in the modern era, because all you know about it is what it means and not how it is applied in so many other industries. So, let us look at why is data science important?

History of Data Science

The confluence of statistics and computers to create quantifiable outcomes in hours was discussed by John Tukey in a 1962 article. The phrase “Data Science” was repeatedly used by Peter Naur in his review of Concise Survey of Computer Methods from 1974. The International Association for Statistical Computing (IASC) was established in 1977 with the goal of combining classical statistical methods, contemporary computer technology, and subject-matter expertise to transform data into knowledge. Exploratory Data Analysis, a paper written by Tukey the same year, outlined the value of using data.

By 1994, organizations had begun assembling vast amounts of personal information for fresh promotion initiatives. Jacob Zahavi emphasized the requirement for new technology in 1999 in order to handle the enormous volume of organizational data.

William S. Cleveland offered an activity plan in 2001 that outlined six areas of study for businesses and institutions and showed how to develop a specialized understanding of data scientists.

The Data Science Journal, which focuses on Data Science subjects such data systems explanation, application, and more, was established in 2002 by the International Council for Science. The Data Science Journal was produced by Columbia University in 2003 as a venue for data teams. The National Science Board presented a collection of digital data that was already available in 2005, and in 2013, IBM stated that 90% of the world’s data had been produced in the previous two years. Organizations at this point understood the value of using data science to transform enormous data clusters into actionable information to acquire important insights.

Why is it So Important?

Until it is transformed into useful information, it has no purpose. Large databases of both organized and unstructured data are mined by data scientists in order to find hidden patterns and derive practical knowledge.

Recently, data science has become increasingly significant. The data transformation is the cause. In the past, the data was in a structured format, was compact, and could be processed by straightforward BI tools.

However, the majority of data nowadays is either semi-structured or unstructured, meaning it takes the form of multimedia such as photos, audio, and videos. Therefore, sophisticated analytical methods that can handle vast volumes of such heterogeneous data are needed for this data.

This is just one of many factors contributing to data science’s current appeal. The profitability and efficiency it provides to firms in various areas are the other primary factors. Data science helps not just businesses but also regular people because it simplifies their daily lives. It continues to show its value in everyday tasks like asking Siri or Alexa for recommendations and more difficult ones like running a self-driving car.

Data science enables businesses to effectively comprehend enormous amounts of data from several sources and to gain insightful information for more informed decisions. It is widely employed in many different business sectors, including marketing, healthcare, banking, finance, and other areas.

The Future of Data Science

Thanks to the documentation of every aspect of consumer interaction, businesses today have access to massive datasets. In order to analyze and develop machine learning models based on this data, data science plays a crucial role. This is due to the fact that these datasets are used to provide insightful data. Therefore, it becomes sense to expect that as analysis and machine learning advance, so will the need for data science.

More positions should become available as the field develops because more data scientists are required for analysis. People who are interested in a profession in data science should anticipate a promising future. In all businesses, it has a very broad application.

Artificial intelligence is a crucial component of data science’s future. The most potent technology that data scientists will have to work with in the future is probably AI. Or to put it another way, data science will evolve in a way that will ultimately improve it. Businesses are already using artificial intelligence to make decisions and maintain operations. Artificial intelligence will be used in real-world scenarios to use automated solutions to sift through massive volumes of data to find patterns that help present firms make better decisions.
