Big Data online classes could have benefits you don't know about...

Computer and information research is a field that is growing rapidly. In fact, the United States Bureau of Labor Statistics expects that the number of job opportunities in this field will grow by 15% from 2019 to 2029[1]. This is much higher than the nationwide average of 4% across all occupations.

Well, big data is one way of getting into the IT world. In fact, the demand for big data specialists is very likely to jump up considerably in the coming years! And even if your current profession has nothing to do with IT and computer science, online courses and degrees make switching careers extremely easy.

Why Study Big Data Online?

Face-to-face education goes back hundreds and thousands of years, but online degrees and courses are becoming the new norm. Some people may look at online education with disdain, but it has a number of advantages that may appeal to big data newcomers:

  • -Plenty of options. With so many big data online courses available, you may choose a topic that you are specifically interested in.
    -Flexible schedule. You may go through online lessons at your own pace. You may evenly spread out your learning efforts over time, or you may complete an entire week worth of material in a day.
    -Low costs. Online classes don’t incur transportation costs, and they are often cheaper than face-to-face classes.

Some of you may still prefer face-to-face learning, but given how the coronavirus pandemic forced people to stay home, this might change for good. But needless to say, you need to investigate your options to determine if online classes are truly for you.

What Can You Learn With Big Data Online Classes?

You can find hundreds of big data courses and degrees on the internet, each with its own curriculum. Among other things, here’s what you could expect to learn with big data online courses [2]:

• The importance of scalable computing over the internet.
• The Hadoop ecosystem.
• How the MapReduce model helps with parallelization and computation distribution.
• The importance of data quality and data security.
• Data modeling approaches and techniques.
• Big data pipelines and workflows.
• How big data integrates with data science and machine learning.

Why Is Big Data Important?

This is merely a glimpse of what big data is. It’s a very involved and diverse field that may take years for you to master. But you have to start somewhere, right?

Now, we should try to better understand what big data is and why it is important in this day and age. If you have doubts about big data, read on.

“Big data” causes a lot of confusion among newcomers. Partly, this is because everyone defines big data differently.

Well, there are two ways to view big data. First, “big data” refers to huge amounts of data that increase in volume and variety with ever-higher velocity [3]. But more commonly these days, “big data” refers to the field that is concerned with finding ways of efficiently and securely storing and processing vast amounts of data.

The issue of efficient handling of data is more important than it has ever been, and it will become even more important in the upcoming years.

In 2010 – fairly recently – the volume of digital information worldwide was 2 zettabytes [4]. For reference, a zettabyte is a billion times more than a terabyte and a trillion times more than a gigabyte [5]. 2 zettabytes sound enormous already. But in 2020, the amount of data worldwide was forecast to reach 59 zettabytes – nearly 30 times more than in 2010! And in 2024, the volume of data is expected to reach 149 zettabytes. Although GPU and CPU technology is today more efficient than ever, one can’t expect modern hardware to brute-force its way through zettabytes of data. To make sure that such amounts of information are efficiently stored and processed in a reasonable amount of time, big data employs a wide range of tools and techniques. You will get acquainted with these if you do decide to get a big data degree or complete an online course.

How Much Do Big Data Engineers Earn?

Data-related fields – big data, data science, and machine learning – are extremely attractive to specialists within and outside the fields of computer and information research. A huge factor in their popularity is high salaries. According to Glassdoor, the base annual salary of big data engineers in the United States is $102,864 [6] as of November 2020. And overall, big data engineer salaries range from $72,000 to $158,000 annually. As is often the case, U.S. data is the easiest to come by, but similar positions in other countries likely have similarly high salary levels.

Online Classes Let You Easily Get Into New Fields

Whether you are looking to launch your career or switch professions, big data online courses and degrees are a great way of doing so. To get started, simply look up your options online.
