Take courses in big data taught by a variety of institutions. Learn about big data analytics and gain skills to advance your education and career.

What is big data?

Big data refers to the analysis of large data sets to find trends, correlations or other insights not visible with smaller data sets or traditional processing methods.1 The exponential growth of internet-connected devices and sensors is a major contributor to the large troves of data that exist today. The storage, processing and analysis of data can require hundreds or thousands of computers. Breaking down the big data definition, an example can be found in the development of the autonomous vehicle. The sensors on self-driving vehicles are capturing millions of data points that can be analyzed to help improve performance and avoid accidents.

Why learn big data?

Analyzing big data allows decision makers to uncover patterns, correlations and insights that can drive future strategy. Big data has become an important part of how businesses operate in nearly every vertical. With the rise of big data comes the need for data professionals, making big data analytics a valuable skill. It’s possible to take big data courses online, making it easier for individuals to manage their education alongside other responsibilities and life events. There are a variety of data analytics programs, courses, and certifications available to help improve a learner’s knowledge about the topic.

Online courses in big data

Through paid and free online courses, individuals can learn the foundations of data science, as well as how big data is stored, processed, and analyzed. Additionally, those pursuing a career in this field can learn how to use key tools and systems for working with big data, such as Azure, Hadoop, and Spark. These skills can help aspiring professionals understand how to design and implement big data analytics solutions. 

Learning about big data may take weeks to months depending on a person’s previous knowledge, educational background and experience as well as the time they can commit to the task and the length of the course(s) taken. Upon completion of big data engineering courses and online big data classes , students may receive a big data certificate as proof of their competence on the subject matter. 

What are examples of big data?

Big data can be used in a variety of contexts across several industries. Examples of how different industries use big data analytics include: 

  • Commerce — Customer loyalty programs allow people to earn coupons, discounts and special offers. In addition to encouraging shoppers to return, these programs provide a lot of data that can be used to optimize which offers are sent to customers based on demographics, trends and their purchase history. 

  • GPS technology — Navigation apps such as Google Maps require constant updates to maintain a positive user experience. Changes in road construction, information about businesses and imagery for the street view function are just a few examples. Google utilizes data from multiple sources, including business submissions, satellite imagery and user location information to ensure maps are accurate and find new ways to improve navigation, like providing traffic information for potential routes. 

  • Healthcare — Data scientists working in healthcare are finding new ways to harness the power of big data to improve patient outcomes. There are many ways data can be leveraged to predict what line of treatment may be best for someone with certain health factors, monitor quality of care in institutions and detect the spread of diseases more effectively.
