Create a use case diagram for (only) 1 of the following systems: GMail, Yahoo Mail, Yahoo Messenger, or YouTube. Choose the system you are most familiar with.
If you choose GMail or Yahoo Mail, include at least the viewing, sending, and deletion of mail messages, as well as user profile maintenance. If you choose Yahoo Messenger, include the sending of instant messages, profile maintenance, and invitation and organization of contacts. If you choose YouTube, include searching, viewing, and posting of videos, and profile maintenance. You should have at least two actors: a typical user and an administrator (you will have to guess the use cases carried out by the administrator).
Final guideline: Once your diagram is complete, you should have at least 8 use cases (ovals) drawn. Use extends and includes links, when possible.
Name your vsd file GMAILlastname1lastname2.vsd, YMAILlastname1lastname2.vsd, YMlastname1lastname2.vsd, or YOUTUBElastname1lastname2.vsd depending of course on the system you end up choosing. Indicate only one last name if you are working alone.
Submit through moodle by the end of the class.
