Hoosier Burger: Well Recognized For

Hoosier Burgeralthough Hoosier Burger Is Well Recognized For Its Fast

Hoosier Burger, renowned for its fast food offerings and the signature Hoosier Burger Special, also serves a variety of plate lunches that include items such as barbecue ribs, grilled steak, meatloaf, and grilled chicken breast. Customers can choose from several side dishes, including roasted garlic mashed potatoes, twice-baked potatoes, coleslaw, corn, baked beans, and Caesar salad. The restaurant caters to downtown business clients who frequently order Hoosier Mighty Meals—combination meals that include a selection of main items and three sides—designed to serve 5, 10, 15, or 20 individuals. To facilitate convenience, Bob and Thelma allow these business accounts to charge their orders, with a monthly bill summarizing all charges sent to each account. Many business customers are repeat clients, often placing the same orders regularly. Bob inquires whether it is possible to track a customer’s order history, and it is confirmed that such tracking is feasible.

Based on this scenario, the following questions are posed: a) What entities does Hoosier Burger need to store information about? b) For each of these entities, what attributes are relevant? c) What identifiers should be used for each entity, and what rules guide their selection? d) Modify the existing ER diagram (Figure 7-10) to include these new entities and specify the cardinalities for each relationship, considering the details provided.

Paper For Above instruction

Hoosier Burger operates as a prominent fast-food establishment with a diverse product portfolio that extends beyond traditional quick-service offerings to include elaborate plate lunches and catered meals for businesses. To effectively model its operations in an information system, it is essential to identify relevant entities, their attributes, and the relationships among them.

Entities and Attributes

The core entities in Hoosier Burger’s system include Customer, Order, Menu Item, Side Dish, Meal, and Bill. The Customer entity captures client information, particularly distinguishing between individual consumers and business clients. Attributes for Customer might include CustomerID, Name, Contact Information, and CustomerType (individual or business). Since the business emphasis involves repeat ordering and charge accounts, a separate entity, BusinessCustomer, extends Customer, incorporating attributes like AccountNumber and billing details.

The Order entity records each transaction, with attributes such as OrderID, Date, and TotalAmount. For recurring business clients, an Order is associated with a specific Customer, especially a BusinessCustomer, facilitating order history tracking. The Meal entity represents predefined meal packages, including Hoosier Mighty Meals; attributes include MealID, Description, Size (number of persons served), and Price.

Menu Item and Side Dish entities detail the menu options. Attributes might include ItemID, Name, Type (main, side), Price, and Description. For meal customization and ordering, a linking entity, OrderDetail, connects Order and MenuItem, including Quantity and SpecialInstructions. The Bill entity captures billing data, with attributes like BillID, BillingDate, AmountDue, and PaymentStatus, linked to Customer and Order entities.

Entity Identifiers and Rules

Each entity requires a unique identifier: CustomerID for Customer, OrderID for Order, ItemID for MenuItem, and BillID for Bill. For BusinessCustomer, a composite identifier combining CustomerID with AccountNumber ensures tracking of multiple accounts per customer if applicable. These identifiers are selected based on their uniqueness, stability over time, and relevance to the entity’s identity.

Overhauled ER Diagram with Relationships

The revised ER diagram incorporates these entities, with relationships such as Customer to Order (one-to-many), Order to OrderDetail (one-to-many), MenuItem to OrderDetail (many-to-many via OrderDetail), and Customer to Bill (one-to-many). The relationship between BusinessCustomer and Order signifies that business clients can place multiple orders and have associated bills. Cardinalities such as one customer to many orders (1:N), one order to many order details (1:N), and many menu items per order (M:N) are specified to reflect the operational details. Additionally, the system would support tracking order history and repeat customers, enabled by foreign keys and relationship constraints.

Conclusion

Developing an accurate ER model for Hoosier Burger involves identifying the key entities involved in its operations, defining clear attributes and identifiers, and establishing relationships with appropriate cardinalities. This model supports functionality such as order tracking, customer history, and billing, ultimately enabling efficient management of restaurant operations and customer service.
