What is SQL?

Plenty of companies use SQL as the standard language for their databases.

By James Nunns

SQL, which stands for Structured Query Language, is considered to be the standard language for relational database management systems and it is used as a way to communicate with a database.

SQL is considered the standard language for relational database management systems. The special-purpose programming language is designed to manage the data within an RDMS, or for stream processing in an RDMS.

The Structured Query Language consists of data definition language, data manipulation language, and data control language and has a scope that includes data insert, query, update and delete, schema creation and modification, and data access control.

 Find out on the next page which databases use SQL.

Databases such as MySQL, Microsoft SQL Server, IBM DB2, Oracle, and Microsoft Access all use SQL where the data is stored in database objects called tables. A table is a collection of related data entries that sit in columns and rows.

Using SQL means that almost any question can be asked of the data in the database, which is good for businesses as it helps them to gain insight into how they are performing and how they can improve.
