SQL (Structured Query Language) is a domain-specific language used for managing and manipulating relational databases. It is designed to interact with databases by defining and manipulating data, as well as performing various operations such as querying data, updating data, inserting new data, and deleting data. SQL provides a standardized way to interact with databases, allowing users to create, modify, and manage databases and their structures. It is widely used in database management systems (DBMS) such as MySQL, PostgreSQL, Oracle, SQL Server, and SQLite, making it a fundamental skill for anyone working with databases.
