Nippon Sushi and Sashimi Shack is a family-owned business operating on the Gulf Coast, currently lacking an effective inventory and order management system. The business purchases seafood and vegetables from local sources and sells through a restaurant, wholesale, and catering services, with prices based on material costs plus markup. Existing manual tracking methods, including journals and spreadsheets, are inefficient and error-prone, leading to difficulties in managing inventory, costs, and pricing. The company requires an object-oriented model for an inventory and order system, including use case, class, sequence, and state transition diagrams to improve accuracy and efficiency.

The development of an efficient inventory and order management system is crucial for Nippon Sushi and Sashimi Shack to sustain its growth and improve operational accuracy. A comprehensive design involves several stages, starting with understanding the various actors, their interactions, and the flow of information within the system. The initial step is creating a use case diagram that depicts the primary functions of the system, including receiving inventory, recording sales, managing purchase orders, and updating inventory status. Actors involved include employees responsible for inventory entry, sales transactions, and management overseeing stock levels and reordering.

For the class diagram, core classes such as InventoryItem, PurchaseOrder, SalesTransaction, Supplier, Customer, and User are essential. The InventoryItem class would contain attributes like itemID, name, type, quantity, cost, and status, while PurchaseOrder would encompass orderID, date, supplierID, items ordered, and total cost. SalesTransaction includes transactionID, date, items sold, sale price, and customer details. Relationships among these classes should reflect ownership and association, such as InventoryItem being associated with PurchaseOrder and SalesTransaction. Inheritance might include subclasses for different food categories like Seafood and Produce, allowing flexibility and extensibility.

The sequence diagram illustrates the process of recording a sale. It begins with the customer placement, followed by the employee selecting items from inventory, confirming availability, calculating the sale price based on current costs and markup, and updating inventory quantities accordingly. The system validates stock levels, processes the transaction, and updates records. For inventory replenishment, the system generates purchase orders when stock levels reach predefined minimums, notifying suppliers, and updating inventory upon receipt. The sequence diagram captures these interactions in chronological order, emphasizing the system's role in streamlining operations and minimizing errors.

The state transition diagram describes changing states of an InventoryItem, such as "In Stock," "Reserved," "Pending Reorder," and "Out of Stock." When new stock arrives, items transition from "Pending Reorder" to "In Stock." When an item is sold, it moves from "In Stock" to "Reserved" (for pending sales) and finally back to "In Stock" once the sale is finalized. If stock runs low, the state switches to "Pending Reorder," and upon dispatching a purchase order, it transitions to that state until replenishment occurs. This diagram captures inventory lifecycle transitions emphasizing automation and precise stock control.
