What is SQL?

SQL, a structured query language, is occasionally pronounced “see-quel.” Relational databases like Oracle, MS SQL Server, Sybase, and others employ ANSI SQL. We use the computer language known as Structured Query Language to interact with a relational database.

All relational database management systems (RDMS), including Oracle, MySQL, Sybase, Informix, Postgres, MS Excel, and SQL Server, use SQL as their standard database language. SQL can manage, organize and retrieve archived data from a computer database.

The DBMS executes the SQL query, collects the required data, and returns it to us. Structured English Query Language, often known as SEQUEL, was the initial term given by IBM.

SQL is used to send a request to retrieve data from the database. SQL statements determine how to structure a data collection or what information should be retrieved or added to a database.
