What is Data Science?
Data science is the practice of utilizing advanced technical skills to uncover valuable insights hidden in the vast amounts of data produced every single day. According to the technology education site Techopedia, “Data science enables the use of theoretical, mathematical, computational, and other practical methods to study and evaluate data. The key objective is to extract required or valuable information that may be used for multiple purposes, such as decision making, product development, trend analysis and forecasting.”
“Data science has quickly emerged as an impactful and essential field and will only continue to grow rapidly in the years ahead. Data scientists will be in-demand and even more specialized to contribute to any possible sector.”
— Dr. Venkat Shastri, Associate Dean of Graduate Programs, De Sanctis Professor of Engineering and Entrepreneurship, and Director of Industry Partnership at the University of San Diego

Data scientists use a combination of advanced skills in coding, mathematics, statistics, analytics, and machine learning to create data-driven insights for their organizations. They are in high demand now that so many businesses have turned to data science and analytics to drive decision-making while emphasizing automation and machine learning as core components of their IT strategies. Tech giant SAS calls them “a new breed of analytical data expert who have the technical skills to solve complex problems – and the curiosity to explore what problems need to be solved.”
Often considered an ideal position from which to advance to a role as a data scientist, data analysts evaluate specific data to generate valuable insights for their employers. To become data scientists, they typically need to boost their level of expertise, particularly their ability to create predictive modeling using machine learning and deploy data science products.
While data scientists are focused primarily on finding new insights from a data set, data engineers are responsible for the production readiness of that data, building the infrastructure and “data pipelines” that other team members use to generate valuable insights for the organization. In addition to building and maintaining an organization’s data pipeline systems, data engineers are tasked with cleaning and “wrangling” data into a usable state.
Data architects are highly skilled technical experts who help companies manage, store, and secure their data, and are focused on working with key stakeholders throughout the organization to create systems and procedures to optimize that data.
Machine Learning Engineer
Often focused on software engineering, machine learning engineers, work on automating predictive modeling, deploying machine learning products, optimizing solutions, and contributing to the field of machine learning and algorithms. According to Springboard.com, “Machine learning engineers sit at the intersection of software engineering and data science. They leverage big data tools and programming frameworks to ensure that the raw data gathered from data pipelines are redefined as data science models that are ready to scale as needed. … They are also responsible for taking theoretical data science models and helping scale them out to production-level models that can handle terabytes of real-time data.”
Business Intelligence Analyst
The core mission of business intelligence (BI) analysts involves using data analytics and data visualization tools and techniques to transform data into insights that drive business value. The biggest difference between a data scientist and a business intelligence analyst may be that BI analysts are focused primarily on interpreting past data to understand trends, while data scientists are more focused on extrapolating past data to develop insights focused on prediction.
Marketing analysts examine sales and marketing data to assess the effectiveness of marketing campaigns, to fine-tune campaigns and to derive insights used for future campaigns. As it has in many domains, technology has revolutionized marketing — providing a vast volume of detailed insights that marketers can use to make their campaigns as effective as possible.
Data Science Salaries
Simply stated, data scientists earn high salaries. The U.S. Bureau of Labor Statistics reports median salaries of $122,840, with the top 10% earning more than $189,780.
A salary survey compiled by Burtchworks.com reports base median salaries of $95,000 to $165,000, depending upon experience. The same survey of 399 data scientists cites higher salaries for data science managers, with median pay ranging from $145,000 to $250,000.
The Burtch Works report also includes detailed information about salaries by region, by industry, and much additional information that is useful to those looking to launch or advance a career in data science.
