What is SQL?

SQL, or Structured Query Language, is a programming language used to manage and manipulate relational databases. Relational databases are organized into tables, and SQL is used to retrieve and manipulate data within those tables.

SQL is a standard language that is supported by all major relational database management systems (RDBMS), including MySQL, PostgreSQL, Oracle, Microsoft SQL Server, and many others. SQL is used to perform a variety of tasks, including creating, modifying, and deleting databases and tables, inserting, updating, and deleting data, and querying data from databases.
