Don't know what is data abstraction

[Sarfaraj Khan]

Hello Guys,

I am Bsc(IT) student with lots of confusion about various concepts of the object oriented programming. I am aware about inheritance, polymorphism concepts. But data abstraction seems very complicate to understand. Is anybody has sound knowledge about the data abstraction concept then please try to share with me. I would greatly appreciate you any help.

Hi,

The data abstraction is a programming technique (which is not unique to functional programming) that involves manipulating data defined in the abstract regardless of how they operate. The phase analysis reveals a number of classes of objects we will have to handle as well as operations associated with them. For example, sets and operations of union, intersection, etc. or lists and basic operations cons, car.

The Data abstraction is a general technique for separating a part, the a program dealing with the details of data representation and secondly, the Part of this program using the data interface between the two parties being clearly defined, it is possible to change one without changing another parts.These data abstraction techniques make programs easier to design and edit. I hope from this information you will get some idea about data abstraction.

Hi friend,

Data abstraction is the process of recognizing and focusing on important characteristics of a situation or object and leaving or filtering out the un-wanted characteristics of that situation or object. And which is not unique to functional programming. The analysis of data abstraction reveals a number of classes of objects we will have to handle as well as operations associated with them.

Abstraction is the process of exhibiting only the essential characteristics of an object depending on programmers view.It is complement to encapsulation. The basic idea of data abstraction is to structure the programs that are to use compound data objects so that they operate on "abstract data.''Data abstraction is a methodology that enables us to isolate how a compound data object is used from the details of how it is constructed from more primitive data objects.

Data Abstraction is the basis for software development. Its through abstraction we define the essential aspects of a system. Data abstraction is a methodology that enables us to isolate how a compound data object is used from the details of how it is constructed from more primitive data objects. The process of identifying the abstractions for a given system is called as Modeling. Data abstraction is a process of representing the essential features
