ABAP ObjectsABAP Objects OO modeling reflects the entities of the reality in a

natural Entities (= instances) encapsulate data and

behavior Supports information hiding Allows reuse of classes by specialization

(inheritance + redefinition) Offers different views on entities by using interfaces Has built-in event handling for loose coupling of
