Western Animal Rescue is a nonprofit organization that supports the fostering and adoption of animals, such as cats, dogs, and birds. People can register to adopt animals. Others register and add animals for adoption. Create the data dictionary structure representing a person registering to adopt an animal. Include name, address (street, city, state or province, zip or mailing code), telephone number, email address, date of birth, current pets (type, breed, age of pet), and references. Each person may have multiple pets and must have at least three references. References must include name, address, telephone number, email address, and how they know the person registering to adopt an animal. Be sure to include notation for repeating elements and optional elements.
