Hi,

normal ABAP is process oriented, where is OOP-ABAP is a new methodology in ABAP which uses object oriented programming.

we have C++, java, C#, etc as OOP languages.

ABAP has also implemented the OOP technology.

it uses classes, methods and interfaces instead of functiongroups and function modules.

As part of SAP’s long-standing commitment to object technology, Release 4.0

of R/3 will contain object-oriented enhancements to the ABAP programming

language. SAP’s object strategy is based on SAP Business Objects and now

covers modeling, programming, interfacing, and workflow. By using principles

like encapsulation, inheritance, and polymorphism, the object-oriented

extensions of ABAP will support real object-oriented development. This will

result in improvements in the areas of reusability, maintenance, and quality of

code. SAP offers an evolutionary approach toward objects which leverages

SAP’s own and its customers’ investments in existing business processes,

functionality and data.

Hi

<b>What is Object Orientation?</b>

Object-oriented programming, is a problem-solving method in which the software solution reflects objects in the real world .

<b>Benefits of Object Orientation</b>

Multiple Instances

Encapsulation - outside vs. Inside

Inheritance

Polymorphism

Explicit interfaces

Control of complexity and dependencies

Maintainability

Foundation for patterns and frameworks

Encapsulation Encapsulation means that the implementation of an object is hidden from other components in the system, so that they cannot make assumptions about the internal status of the object and therefore dependencies on specific implementations do not arise.

Polymorphism Polymorphism (ability to have multiple forms) in the context of object technology signifies that objects in different classes react differently to the same messages.

Inheritance Inheritance defines the implementation relationship between classes, in which one class (the subclass) shares the structure and the behavior defined in one or more other classes (superclasses). Note: ABAP Objects only allows single inheritance.
