What is SQL? SQL (Structured Query Language) is the standard programming language used to manage and manipulate relational databases. It is a powerful tool for interacting with databases, enabling users to retrieve, insert, update, and delete data. In an increasingly data-driven world, SQL is one of the most essential skills for developers, data analysts, and business professionals.
