- Study the following. A customer can place one or more orders, but an order belongs to only one customer. A customer is described by its name, delivery address, and contact number. While an order is described by order number, order status, and order date. Only one payment is made for an order. An order can be paid for through one of two options. A payment is either cash or debit. A payment has an amount attribute. Cash payment is described by cash tendered, while debit payment is described by number, type, and expiry date 6.1 Use the scenario to draw a UML class diagram.Each publisher has a unique name; a mailing address and telephone number are also kept on each publisher. A publisher publishes one or more books; a book is published by exactly one publisher. A book is identified by its ISBN, and other attributes are title, price, and number of pages. Each book is written by one or more authors; an author writes one or more books, potentially for different publishers. Each author is uniquely described by an author ID, and we know each author’s name and address. Each author is paid a certain royalty rate on each book he or she authors, which potentially varies for each book and for each author. An author receives a separate royalty check for each book he or she writes. Each check is identified by its check number, and we also keep track of the date and amount of each check. As you develop the ERD for this problem, follow good data naming guidelines.Create a Crow's Foot ERD for the following description: The KwikTite Corporation operates many factories. Each factory is located in a region, and each region can be "home" to many of KwikTite's factories. Each factory has many employees, but each employee is employed by only one factory.

- Using the Crow’s Foot methodology, create an ERD that can be implemented for a medical clinic, using at least the following business rules: A patient can make many appointments with one or more doctors in the clinic, and a doctor can accept appointments with many patients. However, each appointment is made with only one doctor and one patient. Emergency cases do not require an appointment. However, for appointment management purposes, an emergency is entered in the appointment book as “unscheduled.” If kept, an appointment yields a visit with the doctor specified in the appointment. The visit yields a diagnosis and, when appropriate, treatment. With each visit, the patient’s records are updated to provide a medical history Each patient visit creates a bill. Each patient visit is billed by one doctor, and each doctor can bill many patients. Each bill must be paid. However, a bill may be paid in many installments, and a payment may cover more than one bill. A patient may pay the bill…Using the Crow’s Foot notation, create an ERD that can be implemented for a medical clinic, using the following business rules:- A patient can make many appointments with one or more doctors in the clinic, and a doctor can accept appointments with many patients.
