What is BIG DATA? Introduction, Types, Characteristics, Example

In computer science and computer programming , a data type or simply type is an attribute of data which tells the compiler or interpreter how the programmer intends to use the data. Most programming languages support basic data types of integer numbers of varying sizes , floating-point numbers which approximate real numbers , characters and Booleans. A data type constrains the values that an expression , such as a variable or a function, might take. This data type defines the operations that can be done on the data, the meaning of the data, and the way values of that type can be stored.
