How to Learn Big Data

Organizations and companies collect your data via their products. This may include application data like transactions and user details, or feedback data such as user activity and crash logs. With hundreds of thousands of application instances generating data, it can become difficult to analyze the complete dump. This is where Big Data comes in.

In this guide, we’re going to talk about how to learn Big Data and what resources you can use to master it.

What You Need to Know About Big Data

Big Data refers to data that is excessively huge, high-speed, or complex. This makes it impossible to process this data using traditional processing techniques. Analyzing and drawing conclusions on this data is another tedious task. However, this huge data dump can reap unlimited benefits for businesses if analyzed properly.

Data can directly power a lot of game-changing processes like business analytics, machine learning, and decision-making. And more data relates to better quality output directly. But with increasing data quantity, the overheads on managing this data can become huge, and they can sometimes make this process more costly than beneficial.

Big Data is a concept that aims to solve this problem. Big Data aims to standardize huge data-based operations and make the entire process smooth as well as user-friendly. Some of the most popular characteristics of Big Data are:

  • Volume. The name of the technology itself suggests how important volume is to the subject. Whether or not any collection or store of data can be operated upon using Big Data techniques depends on whether it is big enough to qualify as Big Data.
  • Variety. Apart from handling large volumes of data, Big Data is also characterized by the homogenous nature of data stored. While traditional data processing techniques can easily handle homogeneous data like that stored in spreadsheets and databases, Big Data aims to normalize the same process for complex data, like data coming from monitoring devices, emails, and photos.
  • Velocity. Another crucial characteristic of Big Data is how fast it can handle incoming data. “Fast” refers to the speed at which data is being generated and stored. Big Data is designed to handle data influx that is massive as well as continuous.
  • Variability. A data characteristic that can make processing difficult is the variability of data. Variability refers to the inconsistency shown by data throughout a collection or store. This can hamper traditional data analysis processes. Big Data is designed keeping this in mind and does a good job at efficiently handling data variability.

These are only a few of the many things that technology is built around. As you learn more about Big Data, you’ll become aware of more things you can use to help speed up your learning process.

Skills Needed to Learn Big Data

To learn Big Data, have a basic understanding of how data processing works. You do not need to be an expert in data analysis to understand Big Data, but having a preliminary understanding of the concept will help you get started. 

Big Data originates from the conventional data stores that are processed upon using standard data analysis and processing techniques. Having prior understanding makes it easy to adapt to the advanced concept of handling huge data dumps easily.

Why You Should Learn Big Data

If you are looking to make a career in data-driven decision-making, Big Data is one of the hottest entrants in the market. The technology provides a competitive advantage over other methods of data analysis, and hence serves as a great tool to detect trends and spot patterns useful to a business.

Since Big Data runs on data and not any business-specific technology, it finds its use in almost all industries that involve storing and handling data. Learning Big Data is an investment of your time and resources into a technology that will not go out of trend anytime soon. If anything, Big Data is predicted to become more and more popular in the coming future.

How Long Does It Take to Learn Big Data?

The answer to this question depends on where you currently stand in data handling and processing. If you have some prior experience, three to four weeks should be sufficient to master the various sub-technologies of Big Data like Hadoop and RainStor. If not, you can expect two to three weeks to cover the topics in all its depth.

Expect to devote four to six hours daily for a period of two to three months to get a good grip on the concepts. Mastering any technology is no easy task, and the same goes for Big Data. Expect to spend about six to seven months perfecting your knowledge to show professional excellence in the subject.
