Answer 1

Datatypes are used to identify which type of data we are going to store in the database.

A data type is a collection of data objects and a set of predetermined fined operations

on those objects. A data type in programming specifies the type of value a variable has and what type of logical-mathematical, relational or logical operations can be applied to it without any error.

The different types of Datatypes are:-

• String is used for Alphanumeric characters

Example hello world, Zain, Bus

• Integer is used for Whole numbers

Example:--78, 12, 100

• Float (floating point) is used for Numbers with a decimal point

Example:-3.18, 5.06, 00.11

• Character is used for Encoding text numerically.

Example:-57 (in ASCII, 57 is a lower case 'a')

• Boolean is used for Representing logical values

Example:- TRUE, FALSE
