Which of the following is a layer of object oriented design pyramid?
Which of the following is a layer of object oriented design pyramid?
The correct option is D All of the above
Subsystem layer, class and object layer, message layer are layers of object
oriented design pyramid.
Object oriented design:-
Object oriented designis the concept that
forces programmers to plan out their code in order to have a better flowing
program. The origins of object oriented design are debated, but the first languages
that supported it included Simula and Smalltalk.
1) Subsystem layer:-
The subsystem layer contains a
representation of each of the subsystems that enable the software to achieve
its customer-defined requirements and to implement the technical infrastructure
that supports customer requirements.
2) Class and object layer:-
The class and object layer contains
the class hierarchies that enable the system to be created using
generalizations and increasingly more targeted specializations. This layer also
contains representations of each object.
3) Message layer:-
The message layer contains
the design details that enable each object to communicate with its
collaborators. This layer establishes the external and internal interfaces for
the system.
