What is data abstraction and data hiding in oops concepts?
abstraction is show nonessential data to user ,
What is data abstraction?
Data abstraction is the reduction of a body of data to a simplified representation of the whole. Data abstraction is usually the first step in database design in order to create a simplified framework that can be added to in order to complete the database.
What is physical abstraction in data abstraction?
Physical abstraction in data abstraction refers to hiding the implementation details of how data is stored and accessed. It allows programmers to work with high-level concepts of data without needing to understand the underlying physical structures. This separation enhances modularity and simplifies the complexity of software systems.
Is data hiding and abstraction are same?
no
What are the duties of data abstraction clerk?

What is the difference between data hidding and data abstraction?
Abstraction: Abstraction refers to removal/reduction of irrelevant data or unnecessary data or confidential data from a Class. Data hiding: Data hiding is a feature provided by the abstraction for hiding the data from the class.
Layers of data abstraction in dbms?

Which level of Abstraction describes how data are stored in the data base?

What are the characteristics of OOPS?
Data Encapsulation, Abstraction, Inheritance, Polymorphism
What is data abstraction in c sharp?
Abstraction means that all information exist but only the relevent information is provided to the user. Encapsulation assists abstraction by providing a mean of suppressing the non-essential details.
What is data abstraction give an example?
Data abstraction is the process of simplifying complex data systems by focusing on essential characteristics while hiding unnecessary details. It allows users to interact with data at a higher level without needing to understand the underlying complexities. For example, in a database management system, a user can query data using high-level operations like "SELECT" without needing to know how the data is stored on disk or the specific structures used. This abstraction enhances usability and promotes efficient data manipulation.
Which level of abstraction defines the end user perception of data?
external level
