Cоnsider this scenаriо: A lоcаl bаkery needs a database to manage its daily operations. The bakery serves customers, each identified by a unique customer ID, and stores each customer's name, phone number, and email address. Customers can place multiple orders over time. Each order, identified by a unique order ID, records the order date, pickup or delivery method, total amount, and is linked to both the customer who placed it and the employee who handled it. Employees at the bakery, each with a unique employee ID, have a recorded name, position (such as baker, cashier, or delivery driver), and hourly wage. Orders can contain multiple products, and each product, identified by a unique product ID, has a name, category (such as bread, pastry, or cake), and price. Because products may use special ingredients, the bakery tracks ingredients separately. Each ingredient, identified by a unique ingredient ID, has a name and is supplied by a supplier. Suppliers, each with a unique supplier ID, have a recorded name and contact information. To track which ingredients are used in which products, the bakery maintains a record of all product-ingredient combinations. The bakery also maintains inventory records for both products and ingredients, monitoring current quantities and reorder thresholds. Finally, after each order is completed, an invoice is generated, each identified by a unique invoice ID, recording the payment status (such as paid, pending, or overdue) and the payment method (such as cash, card, or online).
