Learn Big Data: Importance, Skills, and Training Paths

Big data is a growing field that requires skills in computing, programming, networking, database management, statistics, pattern analysis, and business.

Big data is a growing field that requires skills in computing, programming, networking, database management, statistics, pattern analysis, and business. Companies in just about all industries have invested in big data projects across a range of areas, from personalized marketing to road mapping for self-driving vehicles to wearable health device monitoring. Programs that provide opportunities to learn big data skills and related tech concepts offer a big upside to those seeking a solid career in technology.

What Is Big Data?

Big data is the process of dealing with the information that flows into databases in ever-increasing amounts. Data comes from all connected platforms and devices: social media, sensors and devices connected to the Internet of Things, questionnaires and surveys, mobile phone apps, newspaper articles, and many other sources. It’s stored in databases of various sizes and complexity, depending on how much data is collected. These databases are set up to receive high volumes of data and to allow extraction for analysis.

Figuring out what all that data means is perhaps the trickiest part of big data. Cast a net too wide, and too much data may be irrelevant. Cast the net more narrowly, and crucial sets of data could be missing. Data scientists work with database administrators to cast the net just right.

Finding this balance can help companies, government agencies, educational institutions, and nonprofits to thrive. For example, data analysis can help manufacturers to increase efficiency and reduce errors, marketers to identify narrow bands of customers to receive fine-tuned messages, and finance departments to root out wasteful spending and deploy investments to earn greater returns.

The V’s of Big Data

The three V’s help define the answer to “What is big data?”:

  • Volume — the amount of data available, which increases each year
  • Velocity — the speed at which data becomes available, which is getting faster
  • Variety — the forms in which data is presented

Structured data comes in well-ordered, delineated formats such as spreadsheets, which can be readily analyzed. Unstructured data, in which data is embedded in articles, written reports, and social media posts, is harder to deal with.

Big data professionals juggle the three V’s throughout the process of collecting and analyzing data. What’s more, another three V’s have emerged: veracity (data quality), value (business use cases), and variability (data flow variations).

Why Learn Big Data?

It doesn’t take sophisticated analysis to figure out that big data offers many opportunities and rewards. Data analysis is growing as a core competency in business as companies seek that competitive edge.

As such, professionals who have learned big data skills aren’t limited as to where they work. It’s one of those areas of technology that can play a part in just about any business and industry, offering ample opportunity for professionals with the right tech skills to prepare for a big-data related career.

Variety in Big Data Jobs

Businesses in a variety of industries can use big data concepts:

  • Health insurance companies identify risk pools among customers to help set coverage and rates.
  • Researchers compile data on diseases to discover effective treatments, as well as track outbreaks throughout populations.
  • Energy companies examine geological data to discover where to drill for energy or look at weather data to place wind and solar installations.
  • Financial companies analyze data to set risk parameters, assess market volatility, and identify areas for investment.
  • Manufacturers use big data to monitor their manufacturing systems to identify equipment that’s likely to break down and set maintenance schedules.
  • Logistics and delivery firms deploy big data analysis to assign transportation modes, determine routes, manage supply chains, and monitor drivers.
  • Municipal governments distribute resources such as police presence and emergency responders to areas of need as identified by big data.
