In the context of a travel agency,
a) Model the business process "Sell a Trip"
b) Identify Use Cases
c) Create the sequence diagrams for the use cases
Will provide more context to qualified applicants, but It helps to know french as some of the information is in French. Also this is a very simplified basic situation. Trips are considered one item block (meaning we don't have to split transactions into ground, air etc substransactions).
This is to be done ASAP therefore you must (with the little information you have right there) be able to give me an estimate of what you can do (a, b or/and c) within the next 8 hours.
If you know what you are doing this is rather straight forward as there are tons of examples online.
To be considered make sure the first word of your reply is MO88
