How to Become a Big Data Analyst in 2022

A Big data analyst is among the most in-demand career options in the business landscape. It is currently dominating every sector and will continue to do so in the future. Forbes[i], who in 2014 had termed working with big data as the most desirable job of the 21st century, even now holds the same opinion in 2022.  

This is backed by Peer Research [ii]that states that almost 77% of world organizations value big data as a priority. Hence, being a data analyst in current times is your ticket to success and long-term stability. If you are looking for useful pointers for a career in this field then read on.


Who is a data analyst?   

Firstly, let’s erase the confusion between a traditional data analyst and a big data analyst. The former has dominated the business sector for a long time and is concerned with structured data. As data becomes more complex, there is an increasing need for professionals with advanced skill-sets and expertise.

Hence, big data analysts come into the picture, mainly working with raw, unstructured and semi-structured data. Due to its large size, non-traditional data management tools can work on big data efficiently. 

A good example of big data is the New York Stock Exchange [iii]which generates one terabyte of new trade data every day. Another is social media, where sites like Facebook [iv]generate 500+ terabytes of new data per day.

So, it’s a given that the nature of work for a big data analyst and requisite skill-set will differ from the traditional data analyst skills.  


Big data analyst responsibilities

Given that a big data analyst plays a crucial role in the company, their responsibilities are many and varied. Some of them are discussed below:

  • Extracting valuable insights and information from the voluminous data that is collected from diverse sources. This data is further cleaned, organized and processed before it goes off for analysis.

  • Finding newer and alternate sources of data and looking for methods to improve data mining, analysis and reporting.

  • Writing SQL queries for extracting data from the data warehouse.

  • Making data definitions for new database files or making changes to existing ones for the purpose of analysis.

  • Assisting in the decision-making process by presenting reports in various formats- tables, charts, graphs and more.

  • Staying updated with trends and correlational patterns among complex data sets.

  • Checking the performance of data mining systems and fixing any issues.

  • Along with this, a big data analyst may have to collaborate with Data Scientists, the IT team, and the business management team, while working on different organizational goals.

As a data analyst, you are not required to be a fully-fledged programmer, but a big data analyst must have knowledge in coding.

Sound knowledge of statistics and linear algebra is necessary for an analyst who is processing big data. Therefore, they need to be given equal weight. You should be able to understand and work with concepts like summary statistics, probability distribution, hypothesis testing and more.
