SQL stands for Structured Query Language. It is a programming language used to manage and manipulate relational databases. SQL is used to communicate with databases to create, modify, and retrieve data.

SQL is used in a wide range of applications, including e-commerce websites, financial management systems, and data analysis tools. With SQL, you can manage databases of any size and complexity, from simple personal databases to enterprise-level data warehouses.

SQL has several sub-languages, such as Data Definition Language (DDL) for defining database schema, Data Manipulation Language (DML) for retrieving and modifying data, and Data Control Language (DCL) for managing user permissions and access control.

Overall, SQL is an essential tool for managing and analyzing data in various industries, and its popularity continues to grow as more organizations rely on data-driven decision-making.
