What SQL really is?  SQL, which stands for Structured Query Language, is a powerful programming language designed specifically for managing and manipulating relational databases. It allow users to efficiently store, retrieve, and modify data by providing a standardized approach for interacting with databases.

These commands perform various operations, including creating and modifying database structures, inserting, updating, and deleting data, and retrieving information through queries. One of the key strengths of SQL lies in its ability to handle data effectively.
