Major objective of this case study is to discuss Object Design. Object design would be the process of planning for a system of interacting objects when considering solving a software application problem. This case study also focus on to transform an analysis use case to a design use case and construct an ideal object model diagram to model the high-level object interactions for a use case. Finally explain on construct a sequence diagram to model the detailed object interactions and revise an object class diagram to include methods and any additional attributes and relationships.
