What is Data Abstraction in DBMS and what are its three levels?


 Out of hundreds of the things in the code, is it accurate to showcase every detail to the user? 

Do you think hiding unnecessary data from a slot of thousands of elements embedded in an array is easy for a developer? There must be a way out of it! 

You must have heard about data abstraction in DBMS quite a few times! 

This is your ultimate solution for this issue. 

Data abstraction allows you to show or abstract only limited data from the whole database according to your choices. 

It makes analysis, evaluation, and observing the data easier and more convenient for the user. 

 Can you imagine if you show all complicated codes and relations to the user? They will get confused! 

To save the users from such situations, data abstraction is used by the developer. 

Learn everything you need to know about the steps and levels of data abstraction in one article with us!

Stay till the end of this article to know all the important concepts of data abstraction in DBMS. 

What do you mean by data abstraction in DBMS  

You can understand data abstraction as your data filter. 

Data abstraction is simply a process to hide the data you don’t want to display in front of the users. It allows the users to simply stick to the data that is necessary for them to know. 

You can abstract particular data out of a set with the help of this process. You can easily save yourself from errors due to recursion in data structures with this process given that every element can be called out easily. 

 Why do we use data abstraction?

Data abstraction is performed by the developers to carry forward two major tasks. 

The primary task of using data abstraction is to eliminate the data which is inappropriate to be displayed in front of the user. Or simply the kind of data that the user does not require. This way, it becomes easier for the user to use the website and get their work done. 

The second task of data abstraction is to ensure that the data is secured and only a few people can access it. In case you present the unfiltered form of data to the users, your confidential data can reach the wrong hands. 

How does data abstraction work? 

It’s important to filter a huge database 

Data abstraction is done by separating the data from the backend and the one shown to the user. 

Simply put, during data abstraction a new representation of data is formed that is displayed to the user. 

This way, the user only gets access to the useful components and not the internal mechanism of the commands. 

But do you think that all of the data can be scanned and filtered in one go? This is not how it works with data abstraction! 

Data abstraction of a particular set of data is done on four different levels.

Advantages and Limitations of Using Recursion in Programming

Image
Recursion is a popular programming technique that allows functions to call themselves to solve a problem. It is widely used in many programming languages and has its advantages and limitations. In this essay, we will explore both the advantages and limitations of using recursion in programming. Recursion is a powerful programming technique that involves a function calling itself until a certain condition is met. There are several advantages of using recursion in programming: Simplifies complex problems: Recursion is often used to simplify complex problems by breaking them down into smaller, more manageable sub-problems. This makes it easier to understand and solve the problem at hand. Reduces code complexity: Recursive functions can be used to write elegant and concise code by reducing the need for repetitive code blocks. Recursive solutions can often be shorter and more concise than iterative types of sorting . Easy to read and understand: Recursive solutions can be very easy to re...
