Qus:5
Explain the 3 steps in extracting Entity Classes with a flowchart.
Ans:
Steps
in extracting Entity Classes with a flowchart:
Entity class
extraction consists of three steps that are carried out iteratively and incrementally:
·
Functional Modeling. Present scenarios
of all the use cases (a scenario is an instance of a use case).
·
Class Modeling. Determine the entity classes
and their attributes. Then, determine the interrelationships and interactions
between the entity classes. Present this information in the form of a
Qus:6 Explain any 2 phases of Unified Process.
