FILTER EXAMPLE

WHERE WE USE THE SQL AS A APPLICATION

ORACLE SQLSQL : Structural Query Language What is SQL?SQL is Structured Query Language, which is a computer language for storing, manipulating and retrieving data stored in relational database. SQL is the standard language for Relation Database System. All relational database management systems like MySQL, MS Access, Oracle, Sybase, Informix, postgres and SQL Server use SQL as standard database language. Also, they are using different dialects, such as:

1. MS SQL Server using T-SQL, 2. Oracle using PL/SQL, 3. MS Access version of SQL is called JET SQL (native

format) etc.
