This approach takes each use case and extends its requirements in more detail. A use case is a convenient way to document a system’s events. It serves as a kind of table of contents for the business events and activities that must be supported by the system. It will be used to identify how the system will be used and which actors will be involved in which use cases. For the Car Sharing system, the use cases in which we are interested relate to the following activities: membership – from recruitment to termination. accounts and billing. reservations. inventory – vehicles and locations. vehicle usage (completed trips). For this part you will need to develop an overall use case diagram for the Car Sharing IS. This may be formatted as in Figures…arrow_forward

She then prepares the exam paper(with sample solutions), gets it copied to produce enough copies for the class, and hands it out to students on the designated time and location.The students write their answers to exam questions and hand in their papers to the instructor. The instructor then gives the exam papers to theTAs (Test Assistant), along with sample solutions to each question, and gets them to mark it. She then records all marks and returns the papersto the students. Draw a sequence diagram that represents this process. Make sure to show when is each actor participating in the process. Also,show the operation that is carried out during each interaction, and what its arguments are.arrow_forward
