Hi All, I m new to using UML for my applications. I have this stupid confusion about defining use case. I do understand what use cases are, but my problem is how do i separate one from another and what can be clubed in one as a use case. Is there any document, url i can find some help about. For example , consider a simple use case for " User Login" User enters login and password and gets thro is one use case. But then forgot password or wrong login/password , or user clicking on sign me up situations are also use cases or they are just normal path and exceptional path cases. Any help is really appreciated. Thanks - Sagar    More>>
