A package is a container for objects that logically belong together; for example, all of the objects in an application. A package is also a type of development object. An example of a package might be General Ledger Accounting.

When you create a new object or change an existing object, the system asks you to assign the object to a package. When you complete work on a development object like a program, screen, or menu, you generate a runtime version of the object. This runtime version is stored, along with the object, in the Repository.

An application consists of several runtime objects that are processed by the work processes in the SAP System.

Keller H., Kruger S. ABAP Objects: An Introduction to Programming SAP Applications

In a standard SAP installation, development and live operation take place in separate systems. New applications are created in the development system and transported to the production system. Daily work takes place in the production system which uses runtime versions created in the development system.

The division between production and development systems is recommended because changes to an existing ABAP application take immediate effect. To prevent disturbances in daily work flow in the production system, all developments are carried out in development systems designed especially for this purpose.

The Transport Organizer The Transport Organizer is used to move applications from the development system to the production system. It resembles natural English language, making ABAP programs easy to read and understand It's an interpretative language, not compiled.

This nature facilitates testing and running earlier versions of programs without the need for constant compilation. It can be used both from single report list programming report programs to complex transaction processing dialog programs.

It's an event-driven language. It's completely integrated with the rest of the workbench tools, such as the screen painter, the menu painter, the dictionary, and so on.

It supports multilanguage text elements. This means that you can create text elements in several languages without modifying the program source code.

Similar to many programming languages, it includes elements for Variable and data type declarations Flow control elements Event elements Functions and subroutines, which can be managed by a central library It contains a subset of standard SQL statements enabling transparent database table access independently of the underlying database system being used.

It provides extensive functions for handling and operating with data types such as dates, strings, floating point numbers, and so on.

As an object-oriented language, the new ABAP, from release 4.

Basic concepts and features of the ABAP object-oriented programming language are the same as those of other object-oriented languages. The most important are as follows: A business object, or simply an object, represents a type of entity—a customer, a business unit, an account, and so on—containing all its properties.

Every object has an identity that allows it to be distinguished from other objects. Object classes, or simply classes, specify the structure of the objects belonging to a given class and the definition of the interfaces.

Classes are useful for grouping objects with the same structure attributes, methods, events. Generally, objects are defined using classes. The term instance is used for a specific object belonging to a class.

ABAP Objects: Introduction to Programming SAP Applications by Horst Keller

The object's attributes provide the object with its characteristics, describing the current object state. Methods are the actions that can be performed with the object, indicating the behavior of the object.

Events are used so that the object can inform or be informed of any event or state change on the system to enable the system to react to those events.
