What is SQL?
SQL, which stands for Structured Query Language, is the standard programming language used to communicate with relational database management systems. As nearly every aspect of our business and personal lives continue to shift to the digital realm, the demand for people who know how to get access to and manipulate data will continue to grow in the future. You don’t have to be a genius programmer or data analyst to understand SQL either. Most interactions with a database can be accomplished with only 4 basic SQL commands – INSERT, SELECT, UPDATE, and DELETE.
