Difference Between Data Hiding and Abstraction

Object-Oriented Programming languages are a model to find out solutions to real-world problems. Object-Oriented Programming (OOP) is a popular concept. Some of the programming languages like Java is following this concept. The main advantage of Object-Oriented Programming languages is that it simplifies long codes and helps in executing the functions easily. Object-Oriented Programming has now become the basics of all programming languages. Developers are keen to get knowledge in OOPs. Companies also looking for developers who are better at OOPs. OOP is better than a structured programming model to find out solutions to real-world problems.

The design of OOPs is based on two factors, viz Objects, and class. A class can be defined as the plan or a blueprint used to create the objects. The two factors included in the class are attributes and methods. Attributes are termed as the data members which explain the features of the object. And on other hand, the methods explain the behaviors. Classes are used to create objects or in other ways, objects are created by classes. There are two important concepts in Object-Oriented Programming, they are Data Hiding and Data Abstraction. Data Hiding and Data Abstraction are the processes used in Java.

Data Hiding

As the name suggests Data Hiding is a process that hides sensitive and important data. It hides data to save it from attackers. Data Hiding prevents the exposure of important data. It also prevents access to important data by outsiders. In normal terms, data hiding will only hide data components. But Data hiding in java is more like data encapsulation. And it hides private classes and methods too. Data hiding limits the exposure of data and thereby ensures the safety of the data.

Data Abstraction

Data abstraction or Abstraction is the process of extracting the data. As a developer, always deals with data. There are different types of data. These data must be extracted to start a project. To extract data, Data Abstraction is used. In other words, data abstraction can be explained as identifying the needed elements. For every object the properties are different. To get the correct amount of data easily and quickly you need to identify the characteristics and properties of an object. There are abstract classes and abstract methods you need to identify before the data abstraction. Data abstraction is of three types. They are:

• Procedural Abstraction

This abstraction is done in a sequence or order. The procedures or orders will be written one by one as they have to be done. So the abstraction process has to follow the steps for completing the project.

• Data Abstraction

As the name suggests if the abstraction is done from a set of data, then the process is called Data abstraction.

• Control Abstraction

In control abstraction, it is done by using objects. The details of the object will be hidden from the user.

These are the three main types of abstraction. For every developer, abstraction is a key process. In these abstraction processes, only important data are highlighted.

Difference Between Data Hiding and Data Abstraction

Even if these two concepts look similar, they have some differences. Both these concepts are used in programming languages like java for effective and easy work. So let us look at some of the points of difference between Data Hiding and Data Abstraction.

• Meaning

Data hiding is the process of hiding sensitive or important data from outsiders. It is done for safety and to prevent attacks from outside. Whereas Data Abstraction is the process of extracting data. Data abstraction helps to find out relevant information from a given set of information.

• Purpose

Data hiding is done to achieve encapsulation whereas data abstraction aims at reducing the complexity of work.

• Use

Data hiding is used to secure the data from outside attackers and Data abstraction is used for implementing the details.

• Other names

Data Hiding is also called Information Hiding. Data Abstraction is generally called Abstraction.

• Types

Data hiding is not divided into types but Data Abstraction has three types which abstract data in different types.
