Part B Short Answer (Systems Analysis)

(15% - Each question is worth five marks each)

21. Develop an activity diagram based on the following narrative. Note any ambiguities or questions that you have as you develop the model. If you need to make assumptions, also note them.

The following narrative refers to the basic bid submission subsystem of an online auction site such as eBay. While an auction is in progress (i.e., it hasnt reached its termination time), a bidder continues to observe the auction bidding history. If the bidder is currently the bidder with the highest bid, then s/he takes no action other than continuing to observe the bidding history. However, if the bidder does not have the highest bid, then s/he will submit a new bid to the Auctioneer. If the bid is not higher than the current highest bid, then the Auctioneer will reject the bid. If the bid is higher than the current highest bid, then the Auction will accept the bid and update the auction bidding history. This process will continue until the auction terminates. (Note that you do not have to worry about winner determination, bid cancellation, proxy bids, or anything more complicated than basic bid submission.)

22. Refer to the bid submission subsystem of an online auction site such as eBay below. Draw a use case diagram that shows all the actors and use cases.

Bid Submission Subsystem
Use cases	Users/actors
View auction bidding history	Bidder/Auctioneer
Submit new bid	Bidder/Auctioneer
Check bid	Auctioneer
Update auction bidding history	Auctioneer

23. Consider a system that needs to store information about basic activity in an online auction site such as eBay. What are the domain classes that might be included in a model? What are some of the associations among these classes? What are some of the attributes of each class? Draw a domain model class diagram for this system. (Hint: you will need three classes and an association class.)
