What is data type in Python?
Data types are the classification or categorization of data items. It represents the kind of value that tells what operations can be performed on a particular data. Since everything is an object in Python programming, data types are actually classes and variables are instance (object) of these classes.

What is Data example?
Data is defined as facts or figures, or information that’s stored in or used by a computer. An example of data is information collected for a research paper. An example of data is an email. Facts that can be analyzed or used in an effort to gain knowledge or make decisions; information.
What data type is an ID?

How do you choose data type?
The general rule of thumb for choosing a data type for the columns in your tables is to choose the data type that most closely matches the domain of correct values for the column. That means you should try to adhere to the following rules: If the data is numeric, favor SMALLINT, INTEGER, BIGINT, or DECIMAL data types.
How many data types are there in SQL?
SQL data types can be broadly divided into following categories. Numeric data types such as int, tinyint, bigint, float, real etc. Date and Time data types such as Date, Time, Datetime etc. Character and String data types such as char, varchar, text etc.
What is data type float?
The FLOAT data type stores double-precision floating-point numbers with up to 17 significant digits. FLOAT corresponds to IEEE 4-byte floating-point, and to the double data type in C. The range of values for the FLOAT data type is the same as the range of the C double data type on your computer.
What is the difference between real and float?
Real data can hold a value 4 bytes in size, meaning it has 7 digits of precision. Float data can hold 8 bytes, or 15 places after the decimal point. Double data is similar to float, except that it allows for much larger numbers.
What type of data is age?
Age can be both nominal and ordinal data depending on the question types. I.e “How old are you” is a used to collect nominal data while “Are you the first born or What position are you in your family” is used to collect ordinal data. Age becomes ordinal data when there’s some sort of order to it.
What data type is currency?
Currency variables are stored as 64-bit (8-byte) numbers in an integer format, scaled by 10,000 to give a fixed-point number with 15 digits to the left of the decimal point and 4 digits to the right.
What data type is money in SQL?

What is the data type for amount?
The exact numeric types are INTEGER , BIGINT , DECIMAL , NUMERIC , NUMBER , and MONEY . Approximate numeric types, values where the precision needs to be preserved and the scale can be floating. The approximate numeric types are DOUBLE PRECISION , FLOAT , and REAL .
Is real a data type?
A real data type is a data type used in a computer program to represent an approximation of a real number. Because the real numbers are not countable, computers cannot represent them exactly using a finite amount of information. Most often, a computer will use a rational approximation to a real number.
What varchar means?
As the name suggests, varchar means character data that is varying. Also known as Variable Character, it is an indeterminate length string data type. It can hold numbers, letters and special characters.
