Objects have both properties and methods. Properties are attributes of objects that can normally be retrieved and (sometimes) set. For example, many objects expose a Name property, which returns the name of the object. You could use the following statement to retrieve the name of a Form object...
Data types in ABAP are not just attributes of fields, but can be defined in their own right. There are separate name spaces for data objects and data types. This means that a name can at the same time be the name of a data object as well as the name of a data type....
6.3Key-Objects and Object-Oriented Databases A typical question asked in this respect is as follows. It is well known that the object-oriented databases introduced in 1990s were unsuccessful; why another attempt? The idea of object-oriented databases was brought into existence by the triumph of ...
