SQL
First, come first, SQL is one of the most important skills that you must have. While using SQL, a programmer can have an advantage in working with multiple technologies (such as NoSQL).
SQL is the data-centered language that works as a base for the big data era.
Programmers use SQL for multiple operations such as adding, updating, deleting, or modifying any records or tables, and so on. Besides this, RDBM or Relational database management is a crucial part of the field of data science and a data scientist can only control, manipulate or define and query the DB using SQL commands.
Today, some of the modern big data systems (such as Hadoop and Spark) also use SQL only for maintaining the RDBMS (relational database systems) and processing structured data.

Must Have Skills For Big Data Jobs
We all must agree that Big Big data has become the most prominent technology throughout the globe and most businesses are relying on this “Hottest Technology” of the era. Over the period of time, many changes and implementations have been made and that enabled some of the most exciting tools & technology into the mainstream. As for weather forecasting, and data visualization, a dedicated tool has been introduced (one or multiple tools), and so on.
You must be wondering what’s the need for big data in such an industry, well, here are some quick stats to support this,
- Forecasting itself is likely to cross 100 Zettabytes by the end of 2022 and will surpass 180 Zettabytes in the next 5 years (i.e. by 2025).
- There’s no surprise that the figures have drastically grown since the pandemic and more than 95% of the organizations have already started investing in big data and AI.
- A report also suggested that it nearly costs USD 3 Trillion annually to eliminate wasteful data and that’s where big data comes into action to prevent those harms, and the market is likely to cross USD 100 Billion by the end of 2023.
- As of now, Google (one of the giant search engines) holds around 83 percent of the market share, and above 40,000 queries are being pushed via this gigantic search engine. To handle those stats and figures requires a proficient specialist and that’s what makes their job (big data professionals) both demanding and interesting.
So, the primary objective is to get into Big Data and possess the best skills that can fit in any industry that you’ll be working in (and offcourse those skills that are highly in demand). In this article, we will discuss some of the best and most important skills that are required for big data jobs.
