SQL (pronounced s-q-l or sequel) stands for Organized Query Language, a programming language commonly used by professionals working with large amounts of data.
It helps data professionals communicate with relational database systems to clean, sort, extract, and process large data sets. SQL remains highly important to the IT world. According to February 2020 data from Burning Glass Technologies, SQL was the most in-demand skill by tech employers.
Several certifications demonstrate your SQL skills, most of which are vendor or platform specific. If you know what database technology you need to work within your area of interest, you may be able to decide which certification to pursue.

Are SQL Certifications Worth it?
Many jobs that require SQL skills don’t require certification, and employers can often prioritize experience over credentials. However, some hiring managers may look for candidates with the relevant certifications.
Database or SQL certification requirements may be more common for positions that spend significant time on technology from specific sellers or platforms. For example, if a job necessitates experience with Oracle databases, employers may require candidates to be Oracle certified.
A data-related certification can help you compete in what should be a high-demand industry. The field of data science is predictable to experience some of the fastest growth in the coming years. The US Bureau of Labor Statistics projects an above-average growth rate of 22% for computer and information researchers between 2020 and 2030.
