Assignment: UML Diagrams for Online Bookstore System This assignment aims to develop your skills in creating UML (Unified Modeling Language) diagrams. You will apply these skills to model an Online Bookstore System, an e-commerce platform designed for the sale and purchase of books. Through this exercise, you will gain a deeper understanding of system modeling and the practical applications of UML diagrams. System Description The Online Bookstore System is an e-commerce platform that facilitates online book sales and purchases. It includes various functionalities like user account management, book inventory management, ordering, payment processing, and customer reviews. The system interacts with different actors, including customers, administrators, publishers, payment gateways, and shipping services. Assignment Instructions 1. Use Case Diagram Create a Use Case diagram that illustrates the interactions between the system and its actors. Include the following actors: Customers, Administrators, Publishers, Payment Gateway, and Shipping Service. Detail the use cases such as Register, Login, Browse Books, Search Books, Make Payment, Manage User Accounts, etc. Ensure that each actor is connected to the relevant use cases they interact with. 2. Class Diagram Develop a Class Diagram for the system. Identify key classes such as User, Book, Order, ShoppingCart, and Payment. Define the attributes for each class, like userID, username, and password for the User class. Show relationships between classes, including inheritance and associations. For example, the Customer class inherits from the User class, and an Order is associated with multiple Books. 3. Sequence Diagrams Create two Sequence Diagrams. The first should depict the process of a customer making a purchase, including interactions with the ShoppingCart, Payment Gateway, and Shipping Service. The second should illustrate how a Publisher adds a new book to the system, interacting with the Book Catalog and optionally, an Administrator. 4. State Diagram for the Order Class Construct a State Diagram for the Order class. Represent the different states of an order, such as New, Processing, Shipped, Delivered, and Cancelled. Include the transitions between these states triggered by events like order placement, payment confirmation, and order delivery. Submission Guidelines Submit a report containing all the UML diagrams with clear labels and brief explanations of each diagram. Ensure that the diagrams are accurate, complete, and neatly presented. The report should also include a reflective summary discussing the importance of UML diagrams in system modeling and design
