Procedural Approach Vs Object-Oriented Approach in SAP ABAP

Object Orientation in SAP ABAP

Object-oriented programming aims to implement real-world entities like inheritance, polymorphism, etc. in programming. The main aim of OOP is to bind together the data and the functions that operate on them so that no other part of the code can access this data except that function.  Object Orientation was introduced to ABAP to improve its flexibility and versatility in complex business environments. It makes it possible for programmers to structure their code in a more modular and reusable manner....

Key Principles of SAP ABAP:

Objects: ABAP objects are instances of classes that include both data (attributes) and methods (functions or procedures). Objects represent real-world elements or concepts, making complex systems easier to describe and operate with. Attributes: Attributes in ABAP refer to the data or variables associated with a class or object. These attributes define the state or properties of an object and are used to store and manage data within the context of an object-oriented program Methods: Methods in ABAP are the functions or processes that are associated with a class. They define the actions or procedures that may be performed on objects of that class. Methods can be called to change the data of an object or to perform certain tasks. Interfaces: The interface in SAP ABAP is different from the class, it can not have any implementation like the class. It defines a set of method declarations that a class must implement without providing any implementation detail of that method. Interface helps in achieving multiple inheritance. Multiple inheritance can be defined as a class can inherit multiple interfaces. Due to Inheritance interface provides a base for polymorphism because the method declared in the interface behaves differently in different classes. Like class Interface can be defined locally or globally in the ABAP programming language....

Pillars of SAP ABAP:

ABAP(Advanced Business Application Programming) is an object-oriented programming language that supports many oops concepts like other programming languages. It supports all the four pillars of oops i.e. Inheritance, Polymorphism, Abstraction, and Encapsulation....

Procedural Approach Vs Object-Oriented Approach in SAP ABAP:

Below are some of the differences between procedural and object-oriented programming in SAP ABAP:...

Benefits of Object Oriented Approach:

Real-World Entity Modeling: Using object-oriented ABAP, developers may represent real-world things such as clients, commodities, and orders as objects. As a consequence, the code is more understandable and aligned with the business domain. Encapsulation ensures that information stored within objects may only be accessed and altered through certain methods. As a consequence, there is less likelihood of unintentional data change and better data security. Code reuse: By establishing classes and using inheritance, programmers may reuse code in several regions of an application. As a consequence, redundancy is reduced and the development process is made more efficient....
