In BDM, it mentions "equipment". May I ask if I need to include equipment (airplane) in my class diagram? If it is required, I am not sure what methods or attributes should be put in this class.

Please kindly advise. Thanks a lot!

Ei Mandy,

I cannot answer this for you, since it is a architectural design made for you. But i could give you a tip. Read the requirements. ASk yourself: The information about the equipment is essencial for travel reservation system ? (Particurlarly, i don't think so). If you decid that it is a essencial information for the system, so put it in the class diagram. If you do not put it in the diagram, justify it and document down your decision. The certification asks for good arquictects the are able to make decisions. There is no right or wrong decision, there is only, your decision.

And talking about the attribute ans methods, you are not required to put all of them in the class diagram, but you can. I have used only attributed that can clarify the evaluator analysis.

Ps.: Remember that, if you decide to remove the Equipment class from your BDCM, you will remove the relationship between the Seats class, and the Equipment class. So, you will need to justofy this architect decision, in order to explain what should be the system behavior without this relationship.

Best Regards,
