Data is information. Data type defines the type of data - integer, character etc
Actually user defined data type made by user like array,structure,union,pointer. the data type which is define by user or programer according to his need is called user define data type and also called the programer define data type........
struct tm can be an example.
A class is a template to create objects. You define the general behavior of a new data type in a class; then you create objects as specific variables of the new type. In other words, you can consider the class as a data type.A class is a template to create objects.

A built in data type is a framework's native data type. By default you'd probably have some built in generic data types, such as integer, string, boolean and so on. In the other hand sometimes you can extend the framework's data types, by programminga user-defined data type. In this data type you have to define it's behaviour and structure, and once defined, you can use it the same way you use the default data types. In PostgreSQL or Oracle, you can define data types. You can read about it on their webs.
A class is a type. Classes don't do anything except define the type. You have to instantiate an object of the type in order to actually do anything, including initialising data members. However, the class can define how a data member is initialised. The most efficient method of initialising class members if via the class constructor initialisation list.

define judgmental data
A data type defines how data is represented. All data is obviously represented by a sequence of binary values, however, the data type determines how that value is to be interpreted by the language compiler. Object oriented programming languages use classes to define data types, which not only defines the representation of data but also which operations are valid for the type.
what are the different user define data types explain with example
The tags in an HTML document provide a semantic layout for the file. They define what the data is. For instance, the tags define a paragraph.These tags aren't about how the data looks. Instead, the define what the data is.
Don't cheat!
You can define a data-type called 'address': 1. typedef void *address; 2. typedef struct address { char country [32]; char state [32]; ... } address.
