SQL (Structured Query Language) is a programming language used to manage data stored in relational databases, which store structured data in tables. It is used to interact with the data inside the database. SQL skills are always in demand due to high reliance on data. SQL also provides us with a way to extract data from databases for use in BI tools. We can see how big of a role SQL plays in Business Intelligence.
