Question 1 - Sales Purchase Using an activity diagram, represent the actions of a sales purchase, based on the following description: Customers drive their vehicle to a gas pump to purchase gas. Attendants pump the gas into the vehicle. The transaction opens when the attendant lifts the gas nozzle. When the attendant finishes pumping gas and replaces the nozzle, a total is sent to the cashier. Customers must pay for the gas inside the store. At the same time the attendant is pumping gas, the customer can shop for items inside the store. Once the customer is finished shopping and the cashier has received the total from the gas pump, the customer can pay for the transaction. After the cashier accepts payment, the transaction is closed. Question 2 - New Bank Client Using an activity diagram, represent the actions of becoming a new client at a bank and then setting up an account, based on the following description: The bank teller will record your personal client information (name, address, and phone number) in the system. To open an account you (the client) must have a valid identification that will be verified by a bank manager. Once verified, an administrative assistant will scan the identification and the scan will be stored as part of your client record. Clients with verified identification can open up chequing and savings accounts, and the teller will assist with this process. If the client does not have a valid identification, an account cannot be opened at this time. Every newly created account is set to an active state by default. When opening the first account, clients are issued a bankcard by the teller. Clients must select a 4-digitPIN as part of receiving the bankcard. Clients have the option to associate multiple accounts to their bankcard. However, a bankcard must have at least one account associated to it. Show control AND object flow in both diagrams.
