Many thanks for this great tutorial. It is really very clear with good examples and explanation methodology and most probably one of the best UML Tutorial on the web. Hope to come across such kind of good tutorials again…

Yes, “The same extending UseCase can extend more than one UseCase. Furthermore, an extending UseCase may

In reply to Nikko. yes it does. the included use case is always be used everytime the base use case used. it's like when someone's sneezing he always close his eyes. sneezing is the base use case and closing eyes is the included use case.

Found it better than other tutorials…. explaining everything as part of the development process. Thanks, hope to see other tutorials on OOAD and other topics.
