The concept of abstraction relates to the idea of hiding data that are not needed for presentation. The main idea behind data abstraction is to give a clear separation between properties of data type and the associated implementation details.

This separation is achieved in order that the properties of the abstract data type are visible to the user interface and the implementation details are hidden.
Thus, abstraction forms the basic platform for the creation of user-defined data types called objects.

Data abstraction is the process of refining data to its essential form.
