through OOA, Ood, and OOP is abstraction.Ood Modeling uses the graphical Modeling language UML (Unified Modeling Language), UML is a generic modeling language, we experiment with Umbrello for modeling, and Windows recommends that you use STARUML.The result of a process abstraction is a function, and the result of the data abstraction is an abstract data Type,adt, which can be used as an ADT with inherited and polymorphic mechanisms. Data abstraction is the core and origin of OOP. Requi
