SQL is a standard language for accessing and manipulating databases.
Although SQL is an ANSI (American National Standards Institute) standard, there are different versions of the SQL language.

Note: Most of the SQL database programs also have their own proprietary extensions in addition to the SQL standard!

A table is a collection of related data entries and it consists of columns and rows.
