The data type is a label and a guideline for SQL to understand what type of data is expected inside of each column, and it also identifies how SQL will interact with the stored data. In SQL, numbers are defined as either exact or approximate. The exact numeric data types are SMALLINT, INTEGER, BIGINT, NUMERIC (p,s), and DECIMAL (p,s). Exact SQL numeric data type means that the value is stored as a literal representation of the number's value.
