Jacobson's Requirements Model
The Jacobson requirements model includes a problem domain object diagram and use case diagrams. This model defines
the limits and functionality of a system.
Jacobson's Problem Domain Object Diagram
The problem domain object diagram provides a logical view of the system, which is used to specify the use cases for use case diagrams.
