SQL, or Structured Query Language, is a programming language used to manage and manipulate relational databases.

SQL is designed to be used with database management systems (DBMS) such as MySQL, Oracle, and Microsoft SQL Server. SQL is used for various purposes, including data management, data retrieval, and data manipulation. With SQL, users can easily create, modify, and delete database tables, retrieve and update data from the tables, and create complex queries to perform analysis and generate reports. SQL syntax is relatively easy to learn, making it accessible to both novice and experienced developers.

SQL is also highly standardized, which means that its syntax and functions are consistent across different database management systems. SQL has become an essential skill for data analysts, software developers, and database administrators who work with large datasets and need to perform complex data operations.
