The
point of the Use case realisation is to provide a mapping from use cases in the
use case view to the design model in the logical view. This mapping
provides traceability which is important whether an iterative approach is being
used or not.
Usecase realistion view may be used if u r
following iterative model..i,e which helps u to know on which use cases the
work has been performed.Other wise usecase diagram in usecase view and usecase
realistion in logical view are same.

Subject: RE: (ROSE) UseCase View To
Logical View Mapping
Through use case realizations. Each use case
has a corresponding use case realization. A use case realization
exists in the logical view and demonstrates the design elements that
participate in use case realization. It is a use case with a
stereotype of use case realization. Each use case realization should
have a minimum of three diagrams under it:
Participating classes, Dependencies and Basic
Flow. The use case realizations may also have one or more alternative
flow diagrams. The participating classes diagram is a class diagam
showing the classes from the design model that provide the functionality to
realize the use case. The dependencies diagram is a class diagram that
shows the use case realization, the use case it realizes and relates them
using a realizes relationship. This diagram is used for the
traceability between the use case and its realization. The basic flow
diagram is a sequence diagram showing how the dynamic relationship between
the participating classes in the use case realization. It shows the
functionality required by the use case. One or more Alternative flow
diagrams may be used to show any other scenarios the may occur for the use
case. These diagrams will also be sequence
diagrams.
Hi,
What is the
mapping or how is the mapping fro the Use Case View to the Logical View
done?
