System Analysis


In the system analysis phase the system to be built is analyzed using an object-oriented method. The purpose of the phase is to describe the architecture of the system and identify the objects that are needed to implement the required functionality. The models used in this phase are:

The analysis object model is a conventional object model, consisting of class diagrams and possibly state charts, that forms the input to the object design phase. The analysts should in this model be concerned with identifying the objects that must be present in the system. These objects may come from the requirements object model produced in the requirements analysis, or they may be added in this phase for different reasons. For example, objects may be needed to represent the control logic described by the use cases from the requirements analysis. The differences between the object model in the system analysis phase and the object model in the requirements analysis phase are:
