abstraction
In general, the term abstraction refers to the process of identifying
the set of attributes and behavior. of an object that is specific to a particular usage.
This specific view of an object can be designed as a separate object omitting
irrelevant attributes and behavior. The resulting object itself can be referred to as
an abstraction. Note that a given object can have more than one associated
abstraction, each with a distinct usage.
