Must use MS Visio

Question 1) (10 Points) Create a UML Use Case diagram from the following requirements: Tips: (1) Whenever you can say that "Item B is always a type of Item A," or "Item B is always a kind of Item A," that indicates that you have a generalization relationship such that Item B is the specialization and Item A is the generalization; (2) Include relationships are identified when one Use Case always uses another Use Case; (3) Extend relationships are identified when one Use Case sometimes (but not always) uses another Use Case. "Dear Memphis" is a gift store in Memphis and plans to develop an online store system that can handle online orders and manage inventory. The following is the list of requirements that have been identified through interviews with the store manager. Based on the following requirements, develop a use case diagram: Customers can browse and search for products; whenever customers view products, data should be retrieved from the inventory file. Customers can place an order; when placing an order, the customer can either sign in using an existing account or create a new account. When an order is placed, the system must check the inventory file first. When placing an order, the customer must provide payment information, payment can be either a credit card or an electronic check. When payment information is received, an order is saved as a new sale in the sales file. When a new sale is made, the system automatically updates the inventory file. The store manager is able to check the inventory level and generate inventory reports using the inventory file. The inventory manager is able to update the inventory file as new shipments are received from suppliers. USPS provides tracking information which is saved into the tracking data file. Customers can look up tracking information based on the tracking data file, but customers must provide order information first to be able to look up tracking information. The store manager can generate weekly sales reports using the sales file. Sales clerk is a kind of store managers and can use the features available for the store manager, but sales clerks do not have access to the sales file. Question 2) (5 Points) Create a Class diagram from the following requirements: You have been asked to design a digital book store app where users can buy or rent digital books. Create a Class diagram based on the following requirements. Identify classes, attributes, and operations: The app collects and maintains data about digital books, such as title, author(s), genre, and year published. The app collects and maintains data about publishers, such as publisher name, location, representative, and contact information. The store app can "update" the data about digital books. Each publisher must have at least one book in the store and can have many books. In contrast, each book must be associated with only one publisher. Users can create or modify their accounts in the app store, and the apps store collects data about customers, such as name, age, gender, interest, and location. Users can be "individual members or "family" members. Users must be either one of the two membership types (can't be both). Further, every user must choose one of the two membership types. For family members, the app store collects names of family members. There are two types of sales that can be made in the app store: buy and rent. Sales must be either buy or rent (can't be both), and every sale must be either buy or rent. For all sales, the app store collects sales date and sales price. For rent sales, the app store stores "expiration date" and generates expiration notices. Each sale is associated with one user, and a user can have multiple sales. Furthermore, customers have an option to save payment information in the app store (they can save as many payment methods as they want (i.e., multiple credit cards). Payment methods can be credit card or bank account. For credit cards, the app store collects credit card numbers and for bank accounts, the app store collects routing and account numbers
