As a computer language, SQL can be used to store, manipulate or retrieve data from relational databases.
For a relational database, SQL is the standard language. There is a wide variety of relational database management systems (RDMS) that all use SQL as their standard database language.
Such dialects are used, too:
T-SQL, MS SQL Server
the Oracle PL/SQL language

JET SQL (native format) is the name given to the SQL version for MS Access.
There are many reasons why SQL is so popular, including the following:
Relational database management systems can be accessed by users with this tool.
It allows data to be described by its users.
It also allows database users to define and manipulate their own data.
Using SQL modules, libraries, and pre-compilers, it is possible to integrate SQL into other languages.
It's possible for users to add, remove, and rearrange tables and databases.
View, stored procedure, and function creation are all possible with SQL.
Table, procedure, and view permissions can be set by users.
With SQL Tools, it is easy to manage the data to meet users’ needs.
