General programming abstractions are foundational concepts that underlie virtually all of the programming tasks that software developers engage in. By providing a layer of separation from the specifics of the underlying hardware and system details, these abstractions allow for the creation of complex logic in a more approachable and manageable ...
Its development is likely to have been closely connected with the development of human language, which (whether spoken or written) appears to both involve and facilitate abstract thinking. Max Müller suggests interrelationship between metaphor and abstraction in the development of thought and language. [4]
The term abstraction has a number of uses in the field of linguistics. It can denote a process (also called object abstraction) in the development of language, whereby terms become used for concepts further removed from the objects to which they were originally attached. It can also denote a process applied by linguists themselves, whereby ...
The abstraction principle is mentioned in several books. Some of these, together with the formulation if it is succinct, are listed below. Alfred John Cole, Ronald Morrison (1982) An introduction to programming with S-algol: "[Abstraction] when applied to language design is to define all the semantically meaningful syntactic categories in the language and allow an abstraction over them".
Abstraction is the thought process in which ideas are distanced from objects. Abstraction uses a strategy of simplification of detail, wherein formerly concrete details are left ambiguous, vague, or undefined; thus speaking of things in the abstract demands that the listener have an intuitive or common experience with the speaker, if the speaker expects to be understood.
Separate an abstraction (Abstraction) from its implementation (Implementor) by putting them in separate class hierarchies. Implement the Abstraction in terms of (by delegating to) an Implementor object. This enables to configure an Abstraction with an Implementor object at run-time. See also the Unified Modeling Language class and sequence ...
An example of this abstraction process is the generational development of programming language from the first-generation programming language (machine language) to the second-generation programming language (assembly language) and the third-generation programming language (high-level programming language). Each stage can be used as a stepping ...
"Don't repeat yourself" (DRY), also known as "duplication is evil", is a principle of software development aimed at reducing repetition of information which is likely to change, replacing it with abstractions that are less likely to change, or using data normalization which avoids redundancy in the first place.
