    An optimist sees the glass as half full.
    A pessimist sees the glass as half empty.
    A realist drinks it no matter how much there is.

    The most advance usage and great to observe that is
    SQL Queries can be used to retrieve large amounts of
    records from a database quickly and efficiently. Especially for a banking sector these type database are used.

    SQL means Structured Query Language. This language is used to update, deleting and requesting information from databases. It is an ANSI and ISO standard language. SQL database is not static so it can be modified any time .
    SQL divide into two classes.
    (1) DML means Data Manipulation Language
    (2) DDL me and Data Design language

    SQL is a specialized language for updating, deleting, and requesting information from databases. SQL is an ANSI and ISO standard. SQL statements are used to perform tasks such as update data on a database, or retrieve data from a database.

    Every one of them has some quirks in what SQL is accepted. Some (notably SQL Server) allow you to change certain aspects to ANSI mode, but by default they aren't ANSI-compliant.
