Answer / santosh kumar
Abstraction is one of the most powerful and vital features provided by object-oriented programming language. Modularity is very important in any programming language, it provides flexibility to users for using the programming language. This aspect is well achieved with high performance by the concept of abstraction. In object-oriented programming language the programmer can abstract both data and code when needed.

Answer / rohit shori
data abstraction
3 types:-
Physical level describes how a record (e.g., customer) is
stored.
Logical level: describes data stored in database, and the
relationships among the data.
type customer = record
name : string; street :
string; city : integer; end;
View level: application programs hide details of data
types. Views can also hide information (e.g., salary) for
security purposes.

Answer / prasenjit chatterjee
Abstraction means that just represents the essential
feature of some thing without including much details.
So the data abstraction means that does't define the
internal structure of the data, but allows difference
operations on it. Such data types are called abstract data
type or (ADT), like stack queues are the example of an
abstract data type
