State about the Object models
Object models are used for explaining the objects in the system and their connection with each other in the system. The dynamic model explains interface among objects and information flow in the system. The data transformations in the system are explained by a functional model. All three models are equally valid during all stages of designing. These models handle the liability of acquiring execution details of the system development. It is crucial to note that you cannot define a system totally until unless all three models are defined properly.
? Actor: Actor shows an external user / end user who interact with the system. ? Object: Object is shown by one of components of the system. ? Unit: A unit is a subsystem, o
