abstraction
1. Generalisation; ignoring or hiding details to capture some kind of commonality between different instances. Examples are abstract data types (the representation details are hidden), abstract syntax (the details of the concrete syntax are ignored), abstract interpretation (details are ignored to analyse specific properties).
2. <programming> Parameterisation, making something a function of something else. Examples are lambda abstractions (making a term into a function of some variable), higher-order functions (parameters are functions), bracket abstraction (making a term into a function of a variable).
Opposite of concretisation.

Abstraction
The process of picking out (abstracting) common features of objects and procedures. A programmer would use abstraction, for example, to note that two functions perform almost the same task and can be combined into a single function. Abstraction is one of the most important techniques in software engineering and is closely related to two other important techniques -- encapsulation and information hiding. All three techniques are used to reduce complexity.

Abstraction
(a.)
The taking surreptitiously for one's own use part of the property of another; purloining.
(a.)
The act process of leaving out of consideration one or more properties of a complex object so as to attend to others; analysis. Thus, when the mind considers the form of a tree by itself, or the color of the leaves as separate from their size or figure, the act is called abstraction. So, also, when it considers whiteness, softness, virtue, existence, as separate from any particular objects.
(a.)
The act of abstracting, separating, or withdrawing, or the state of being withdrawn; withdrawal.
(a.)
An idea or notion of an abstract, or theoretical nature; as, to fight for mere abstractions.
(a.)
Absence or absorption of mind; inattention to present objects.
(a.)
A separation of volatile parts by the act of distillation.
(a.)
A separation from worldly objects; a recluse life; as, a hermit's abstraction.

ABSTRACTION
[L:100] One of three logical acts of the understanding "by which concepts are generated as to their form", the others being comparison and reflection. Abstraction is "the segregation of everything else by which given presentations differ....the most abstract concept is that which has nothing in common with any concept differing from it. This is the concept of something; for what is different from it is nothing".

Abstraction
This article is about the concept of abstraction in general. For other uses, see abstraction (disambiguation).
Abstraction is the process of generalization by reducing the information content of a concept or an observable phenomenon, typically in order to retain only information which is relevant for a particular purpose. For example, abstracting a leather soccer ball to a ball retains only the information on general ball attributes and behaviour. Similarly, abstracting an emotional state to happiness reduces the amount of information conveyed about the emotional state.| See more at Wikipedia.org... |
