Hi,

I'm working on Big Smokes assignment. Business Domain Model (BDM) lists Standard/Petite/Flavored cigars as entities. I feel that when it comes down to class diagram and persistence Standard/Petite/Flavored is just a category.
I've done excessive study online of cigar selling stores, all cigar have pretty much same attributes regardless whether they are flavored or petite.
Also, I've seen that in real life there are much more categories than just these 3. So it's likely that as soon as BigSmoles online store goes into UAT phase it would become a must-have feature. Therefore I feel that I need to design something that would be extensible enough to allow that.

I've read somewhere that my class diagram *must* depict all entities from the BDM. If I go with "categories" I would not have classes like
FlavoredCigar <<@entity>>
StandardCigar <<@entity>>
PetitteCigar <<@entity>>
but rather
Cigar <<@entity>> with all the attributes.

Question: How do I make sure that I've shown that these three important categories are supported by my design?
One solution that came to my mind - is to provide Object diagram along with my Class diagram and that on that Object diagram show these Categories

P.S.
I've read "Position on real assignment" I don't feel like my post reveal any solution details.
For this question

1)When does a problem with using persistent cookies or client certificates for
user authentication occur?
Choice 1 When a user changes computers.
Choice 2 When a user does not log on for more than 30 days.
Choice 3 When the IP address of the server changes.
Choice 4 When the IP address of the user changes.
Choice 5 When a user wishes to change preferences.



I'm in doubt - but if asked I would go for choice 1, as IP address change is irrelevant.
For question #8
Correct Answer is Choice 3

Choice 1 Programming is often specialized. true
Choice 2 Most internal networks change daily, requiring programming changes. true
Choice 3 Only works for TCP packets, not UDP. false
Choice 4 Extensive filter lists slow the routing process. true
Choice 5 Can be easily compromised or defeated. true
Hi Dmitry,

Do you think that Idea has lost the battle with Eclipse? Looking at the market share it's definitely seems so. What Intellij is planning to do about it? Would you say that these two IDEs are for different target groups?
How do I know the cost of Part II then? All the links lead to Prometrics
Once I register at sun website who do I pay?
Hi,

How do you book and pay for the test?
The Sun website says that the SUN CERTIFIED ENTERPRISE ARCHITECT FOR J2EE(tm) TECHNOLOGY exam consist of three steps. I can only find pricing for two at the www.Prometric.com
310-051 - SUN CERTIFIED ENTERPRISE ARCHITECT FOR J2EE(tm) TECHNOLOGY 200 USD
310-061 - SUN CERTIFIED ENTERPRISE ARCHITECT FOR J2EE (TM), PART III - 200 USD

what about the second step? about this one Step 2 - Sun Certified Enterprise Architect for the Java 2 Platform, Enterprise Edition - Assignment (CX-310-300A)? Where to book it?

I even called prometrics this morning, the lady on the other side could not help me.
