Object-oriented programming (OOP) is a programming paradigm based on the concept of objects, [1] which can contain data and code: data in the form of fields (often known as attributes or properties), and code in the form of procedures (often known as methods).
In class-based programming, a factory is an abstraction of a constructor of a class, while in prototype-based programming a factory is an abstraction of a prototype object. A constructor is concrete in that it creates objects as instances of one class, and by a specified process (class instantiation), while a factory can create objects by instantiating various classes, or by using other ...
The ABAP Development Tools (ADT), formally known as "ABAP in Eclipse", is a set of plugins for the Eclipse IDE to develop ABAP objects. [ 6 ] In this scenario, the ABAP developer installs the required tools on his computer and works locally, whereas a continuous synchronization with the backend is performed.

In object-oriented programming, analysis and design, object identity is the fundamental property of every object that it is distinct from other objects. Objects have identity – are distinct – even when they are otherwise indistinguishable, i.e. equal.
In object-oriented programming, a composite is an object designed as a composition of one-or-more similar objects, all exhibiting similar functionality. This is known as a "has-a" relationship between objects. [4] The key concept is that you can manipulate a single instance of the object just as you would manipulate a group of them.
Many object-oriented programming languages permit a class or object to replace the implementation of an aspect—typically a behavior—that it has inherited. This process is called overriding . Overriding introduces a complication: which version of the behavior does an instance of the inherited class use—the one that is part of its own class ...
The principle plays a central role in design patterns in object-oriented programming, although most writings on that topic do not give a name to the principle. The Design Patterns book by the Gang of Four, states: "The focus here is encapsulating the concept that varies, a theme of many design patterns." This statement has been rephrased by ...
