Consider the following scenario then complete the exercises below: Before a resident can attend a recreational activity, both the resident and the activity must be entered into the system. Every resident must have a valid resident number in order to attend a recreational activity. Residents can attend up to 10 recreational activities a month free of charge. Additional activities are charged a fee that is specific to the activity. Every time a resident signs up for an activity, the system must ensure that they have not exceeded their limit of free activities and that the seat limit for the recreational activity has not been exceeded. If the resident has exceeded their limit then the system must note that the resident will be charged for the activity. If the seat limit for the activity has been reached, the resident should get a message telling them that the activity is full. Ms. Smith assigns one of her staff to enter all the planned recreational activities into the system. Her staff will enter all the activity information including date, time, duration, location, seat limit, fee, and staff. The staff can also edit and delete the activity information. Every week the office manager also creates a newsletter that is sent to current residents. This newsletter includes information about upcoming activities. Every morning, the office manager prints a report that lists all the residents who have reached their 10 free recreational activities. If a resident has reached the threshold, the manager calls the resident to let them know. If they don’t reach the resident the manager will then send an email. Exercises: 1. Using the Use Case diagram you created for the HRC scenario, create a Sequence diagram for the "Resident Register for Event" use case scenario and the "Office Manager Weekly Activity Notification" use case scenario. The "Resident Register for Event" use case scenario should assume that the resident has a valid resident ID and should also check for activity limits. 2. Create a Communication diagram for the "Office Manager Create Monthly Bill" use case scenario. This use case scenario has the following Normal Flow of events: a. Manager gets list of residents who have attended > 10 activities. b. For each resident, the manager will get the fee for each additional activity. c. Manager calculates the total bill. d. Manager creates a bill notification in the system and updates the residents account with charges. e. When the resident has paid their bill, the manager updates the residents account. Create a State Machine Diagram for the "Resident" class and for the "Activity" class.
