SQL, short for Structured Query Language, is a standardized programming language used for managing and manipulating relational databases. SQL can be used to create, modify, and delete database structures and records.
It allows users to query data, retrieve specific data, update data, delete data, and create and modify database schema structures. SQL is highly popular due to its flexibility, power, and widespread adoption in the tech industry.
There are several different types of SQL, including MySQL, SQLite, and PostgreSQL, each with its own specific features, but all follow the same basic structure and command set. SQL is declarative, which means you describe what you want, and the database management system figures out how to do it.
