What Is Abstraction In Programming Language

In object oriented programming languages such as c object pascal or java the concept of abstraction has itself become a declarative statement using the keywords virtual in c or abstract and interface in java. In software engineering and programming language theory the abstraction principle or the principle of abstraction is a basic dictum that aims to reduce duplication of information in a program usually with emphasis on code duplication whenever practical by making use of abstractions provided by the programming language or software libraries. You just write what data you are concerned with without paying heed to how it is stored in or retrieved from the database.

Decomposing problems using this technique yields a hierarchy of objects.

What is abstraction in programming language. Abstraction is a fundamental principle in some types of computer science. That enables the user to implement more complex logic on top of the provided abstraction without understanding or even thinking about all the hidden complexity. Hierarchies of objects are usually limited to three levels maximum for ease of maintenance. Abstraction from the latin abs meaning away from and trahere meaning to draw is the process of taking away or removing characteristics from something in order to reduce it to a set of essential characteristics.

Its also one of the least understood ideas in programming partially for semantic reasons. Abstraction is a design technique wherein you analyze and create groups of similar things using their public behaviors as classification guide. Its main goal is to handle complexity by hiding unnecessary details from the user. There is a difference between the low level abstraction offered by primitive data types in a language like string and the data types you can create in modern programming languages often using objects.

Data abstraction is the programming process of creating a data type usually a class that hides the details of the data representation in order to make the data type easier to work with. In object oriented programming abstraction is one of three central principles along with encapsulation and inheritance. Different programming languages provide different types of abstraction depending on the intended applications for the language. These data types are called abstract data type adt.

Think of how you write sql queries to interact with a database. This abstraction definition is used in object oriented programming as mentioned above in cooperation with two other central principles encapsulation and inheritance. The word abstraction refers to the process of removing particular characteristics from something in attempts to reduce it to only those that are essential. The high level programming languages are an abstraction on top of machine or assembly language.

Abstraction is one of the key concepts of object oriented programming oop languages. It is a key design aspect of object oriented programming languages and application programming interfaces.
