Solution

Data abstraction is a programming concept where complex data is simplified by only showing relevant details to the user. It hides the background details and emphasizes on essential points.

Here are the steps to understand it:

  1. Conceptualization: In data abstraction, you start by identifying what data your software or program will need to operate.

  2. Simplification: After identifying the necessary data, you simplify it by breaking it down into smaller, more manageable parts. This is done by creating classes or objects that represent the data.

  3. Hiding Details: The next step is to hide the details of how the data is stored and managed. This is done by creating methods that allow the user to access and manipulate the data without knowing the details of how it is stored.

  4. Accessing Data: The final step is to provide a way for the user to access the data. This is done by creating public methods that allow the user to get and set the values of the data.

In summary, data abstraction is a way to simplify complex data structures by hiding the details of how the data is stored and managed, and providing a simple way for the user to interact with the data.
