Hi All,

I am working on creating a UML design for a CaseStudy. I would like to know what is the best approach to identiy class, attributes, operations and relations from a UseCase. Currently i am using Noun phrase approach but i am facing difficulty in identifying the Analysis classes correctly( i am missing few classes ).

I hereby request you to please suggest me best technique used to identiy below

* Classes, Attributes and it's methods
* Class Relations
* Associations
* Multiplicity[

Thanks in Advance.

Regards,
Vasu

You can try this approach,
Draw the Activity digaram based of on the use cases.Try to derive the classses from Activity digaram.

If you follow the use case description and its steps thoroughly. To achieve a scenario in that use case from UI to domain model, you will cover most of the required classes that are to be present for a use case.
