Hi,
I have a few questions about part II and I hope somebody can help me.
1. Can we change the business data model?
If we can change the business data model, then can we change the use cases?
2. Regarding the class diagrams, at the first glance, I found there would be too many classes in the diagram if we put all the classes in. So perhaps we will have two choices:
. put related classes into a package. And then draw a package diagram.
. do not put all the classes, just put the important classes, such as classes direcly related with the business model and key controller classes.
I prefer the second choice. My question is if there is a guide line for EJB classes in UML. I.e, each EJB has three classes, shall we put all the three or just one?
3. Anybody recently downloaded togethersoft? I downloaded one, but could not get a license key.
Thanks in advance,
John

You can not change the model but you could enhance it.
2. Regarding the class diagrams...
Add only importnat classes, you do not have to put all 3 EJB classes 1 would be enough. You have to put calsses- packages will not do.
3.Togethersoft
If you download and provide an already used email address- they don't send a key. You have to use a new email each time.
