Hi guys,

I was silent reader of this forum for a while. I am working on the assignment now; and I need some clarification about the approach.

First two use cases are completely the same (with different titles only). I am wandering if I need to extend the second one to complete process described as a title when I am preparing the sequence diagram.

Also, both use cases define that some design is already selected (but it does not describe the selection process in the use case). Do I need to include that selection process in the sequence diagram or I can consider it as precondition?

Thanks,
Ivy

Ivy,
Congrats on your first post! I wrestled with whether to delete it because if felt like the post would quickly stray into discussing a specific assignment too much. I went with removing the assignment name from the subject. If this can be discussed without being about or requiring knowledge of an assignment, it is ok. If not, then it shouldn't be discussed here anyway.

Now on to your questions

1) It seems unlikely that the use cases are exactly the same. It is possible you are missing something subtle or one is a subset of the other or the like.
2) Yes. You can document a precondition rather than repeating yourself in the second sequence diagram.

This was discussed in another thread and it seems this assignment has been changed by Oracle but they may have made a mistake with the Use Cases. If I was you I would do the assignment as set out in the instructions but maybe mention in the assumptions that both are the same and include the instructions in with your submission. You may also want to email Oracle but don't hold your breath for a reply...

good luck!

Yes, I noticed the other thread with the same discussion.


Thanks Jeanne. I did not want to go in details, but these use cases are the same in my assignment (I know it sounds strange). I wanted to make sure that I am not the only person with this strange use cases.

Thanks!
