Give the Introduction of OBJECT DESIGN
Strategies which are selected during system design are carried out in object-oriented design. In this procedure, objects which are identified in the analysis are implemented in a way that it minimizes memory usage, other associated costs and execution time. All this is done by selection of appropriate algorithms, by enforcing proper controls and optimizations.
In this section, we will cover the ideas of object design for process, proper algorithm selections, control implementation and design optimization, with proper adjustment of the inheritance.
