Big data is transforming businesses and driving growth throughout the global economy.
Businesses across all industries have benefited by using big data to protect their databases, aggregate large volumes of information, and make better-informed decisions. The financial industry, for example, uses big data as a crucial tool to make profitable decisions, while other data organizations consider it an asset to protect against fraud and detect patterns in large datasets.
What is Big Data?
Big data is a field that deals with massive data sets that are too complex to manage using traditional data management methods. Organizations mine unstructured and structured data, leveraging machine learning and predictive modeling techniques to extract meaningful insights. With these findings, managers are able to make data-driven decisions that solve key business problems.
There are several technical skills that individuals must acquire to succeed in this field, including data mining, data visualization, programming, and other analytics skills. Due to the various challenges in learning these skills, the need for professionals in this field continues to increase, making the big data field a sought-after career path.

A guide to what you need to know, from the industry’s most popular positions to today’s sought-after data skills.
Is Big Data Still in Demand?
The U.S. Bureau of Labor Statistics (BLS) anticipates data-related occupations will grow by more than 31 percent by 2030, creating a plethora of new jobs in the same time period. Increasingly, top companies are in need of qualified professionals to fill those emerging roles. However, professionals with these specialized skills are difficult to find, meaning data jobs pay quite well for those with the right expertise.
Salaries for big data careers are increasing just as quickly as the demand for skilled professionals. Many of these jobs report compensation well into the six-figure range and above market value in order to compete in the talent war.
Is a Degree Needed for a Big Data Career?
A majority of these jobs require candidates with both experience and advanced degrees. In a fast-growing field, that’s not easy to find. Eighty-one percent of all data science and analytics job postings seek workers with at least three years of prior work experience, and 39 percent of these roles—the highest-paying ones, in particular—require a relevant master’s degree.
An important factor to remember is that senior data analysts, business analysts, and other big data professionals will most likely differ in the kinds of degrees they pursued to get into the field.
Master of Science degrees are the overarching similarity for these professionals;, however, their education can vary in what areas they focus on, such as data science or business analytics. Regardless of which specialization they choose, individuals with a relevant master’s degree in big data can look forward to generating a successful career in this incredibly lucrative industry.
But which big data careers pay the highest? Here’s a look at the most coveted positions, their salaries, and the skills you’ll need to qualify.
