Data Independence: The Most Up-to-Date Encyclopedia



Data independence in DBMS is a feature of database management systems that enables programmers to change information definitions and organization without impacting the programs or applications that use it. 

Irrespective of any modifications made to the data, such a characteristic enables several users to access and process the exact data for varied purposes. 

The ability to change one level of database management systems without impacting the data structure of DBMS or access procedures of the next higher level is known as data independence.

Data independence enables admins to keep information independent from the apps and programs that use it. As a result, programmers don't have to rewrite their source codes every time the data properties change. 

Most significantly, this quality reduces errors while saving time and other assets.


Overview of Data Independence

Types of Data Independence

Physical and logical data independence are the two types of data independence in DBMS, depending on the levels of data abstraction.

Physical Data Independence

The ability to alter the physical structure of the data without impacting the conceptual level is referred to as physical data independence in DBMS...

What are the 5 types of inheritance?

Image
  The concept of inheritance is considered among the most crucial concepts of object-oriented programming. Inheritance in Java is considered as a process where one class inherits the property of its parent class. When we simply define inheritance, we call it the capability of a class that derives the properties or features of other classes. The new class will be created as the ‘ derived class’ and the existing class will be known as base or parent class. Talking about the types of inheritance, it is generally of five types. Here, in this blog we are going to discuss all these inheritance types in detail with the help of examples. Without any ado, let’s get started! Types of inheritance In case of inheritance, one class derives the properties from its parent class. Here, any new class will be derived from its existing class. This new class is the derived class and our current class will be termed as the base class. When we talk about inheritance in Java, there are mainly five types ...

Remove duplicates from a sorted linked list

Image
Introduction Before reading this article, It is recommended to have an understanding of the linked list and its implementation and some basic operations on the linked list. Problem Description Create a function that takes a non-descending list and removes any duplicate nodes. Only one traversal of the list is necessary. Eg. Consider the given linked list: 1->1->1->2->2->3, the function is expected to convert the linked list into 1->2->3. In this article, we will extensively discuss the Label Control in C# & how to  remove duplicates from sorted doubly linked list .  Important:  We are supposed to delete only the duplicates i.e. only one copy of nodes should be there. Intuition:  The biggest hint given is that the list is sorted or non-decreasing in nature. From this, we can deduce that if duplicates are present, then it has to be the next one in the chain. The ideal way to approach this problem is to simply loop through the first value i...
