Customers placeorders by telephone, by mailing an order form included with each catalog, or via the Website.When customer orders come in, the item master and the customer master files are bothupdated. If an item is out of stock, the inventory control department is notified.

Produce a Class Diagram and a Use case diagram for the State Patrol case. You should list assumptions and questions that are relevant and functionally determine your model Things to help: When you create the Use Diagram, you should start with the basis that there are 3 roles: Officer (because the Officer is entering the ticket online directly from the patrol car) Motor Vehicles clerk Court clerk (Note the "Driver" is not a role since her/his pleas (or payment) are probably being entered by a clerk) If you have already defined an ERD solution for this case (in class), converting this to a class diagram should be relatively easy.
Make a UML Class Diagram based on the following scenario: As a Software Analyst in Techno Bhd., you have been assigned by your Project Manager to model an SUV Rental Provider App using UML. The SUV Rental Provider App has two types of system users namely Client and Admin. The client, who can be Member or Non-Member can search for SUV models and daily rental. Each SUV model consists of SUV model details and daily rental. Thus, the Client can choose to view the SUV model details such as description and images and daily rental based on the types of the selected model. Only Member and Admin are required to log in to access the system. Member gains access to additional services. The additional services for members are: manage a reservation, check membership details, change password, manage credit card and banking information, and log out. Each Member is entitled to reserve up to 10 SUVs. When a member makes a reservation, he/she has to specify the selected SUV model and the number of rental…
