What is data science? How to make a career in it?

Ever since the world started to advance toward digitalization, numerous tasks have been made more convenient and effortless and that includes data storage as well. With countless activities happening through digital means, the amount of data stored in databases is also huge. 

It is also true that these data are very useful for many entities like businesses and the government of a country. But how do we know which data is valuable and meaningful for a specific purpose? This is where the concept of Data science enters. It is a notion where data scientists study and extract meaningful conclusions from the information stored.  

Although data science is related to the IT sector, almost every industry, from medicine, retail, finance, and telecom to agriculture uses data science to make their work less time-consuming and get the best solution for customer satisfaction.

A report also backs the growth of data scientists' jobs by stating that by 2026 the number of data science-related jobs will reach 11.5 million at the global level. 


So if you are thinking of making a career in data science, then go for it, because in the coming years it is only going to grow more. Let's understand the fundamental knowledge of data science. 

What is data science?

Data science is an approach where data scientists study extensive amounts of information to pull out the required and meaningful data from a database using different analytical tools and techniques to analyze and tackle real-world problems in an organization.  

Being multidisciplinary, it includes many fields of study within it such as mathematics, computer science, artificial intelligence, statistics, machine learning, algorithms, coding, and business intelligence.

Data science is all about gathering raw data, processing them in a way that they can be used, summarizing it by studying the patterns, analyzing the data using different methods, and preparing it in the form of charts and graphs so that it can be understood and used in the decision-making process.

How to start a career in data science?

Just like any other career option, data science also involves certain requirements in education, skills, work experience, etc. Let’s understand the qualifications needed for excelling in data science.

Education required to start a career in data science 

To start a career in data science, a bachelor's degree in business, data science, mathematics, statistics, information technology or any other related field is required. In case your degree is from an unrelated field like literature, you can take up short  certification courses that will  introduce you and guide you to the path of data science. You can choose to learn skill-specific certification courses as well namely, machine learning or any programming language course. 

Some jobs  in data science demand a mandatory bachelor's degree, while for others it is possible to enter with a certification as well.  Getting a master's degree can strengthen your chance for senior roles in the field.    

Skills required to start a career in data science

A job in the field of data skills requires some skills that are required: .
