Introduction

The digital transformation has motivated industries to adopt a new approach towards business operations. Today, every business ranging from small companies to Fortune 5 organizations is powered by data to gain insights into their business and market scenarios.

Efficient data management becomes a priority with an enormous amount of data being generated daily. Therefore, the demand for database administration professionals has increased tremendously in recent years.

Although SQL databases have been existing in the IT industry for decades, it is still considered useful. SQL continues to be the core of every corporation’s backend and a vital factor in the field of data analytics. Thus, a career as a database developer or a SQL developer is a lucrative job position among the industry’s highest-paying jobs.

However, getting a grasp of a new skill or upgrading skills from the ground up is a daunting task, especially when learning an entirely new programming language.

Luckily, with the emergence of the online platform, several top-tier universities and other educational institutions offer in-depth courses covering all SQL aspects. However, the roadblock occurs due to a wide range of offerings, and some of the courses don’t meet the learners’ expectations.

Thus, it becomes essential to find the appropriate course that provides a well-balanced curriculum with theory and builds the hands-on experience with a keen eye on the cost factor and schedule. The article deep dives further and explores some of the most popular courses available on the online platform currently.
