When a new customer comes to the Animal Hospital, the parents of the pets are required to complete an introductory form that includes the following:

• Parent name
• Address
• Day phone
• Evening phone

The parents are also required to provide the following information about each pet (Note: some people own many pets!):

• Pet name
• Breed
• Color
• Birth date

The introductory information is to be stored so parents do not have to provide the same information each time a pet has an appointment.

The doctors see only one pet during each appointment. For example, if Dr. Waikato is going to see Emilys two cats, then two appointments are established. For each appointment, the pets weight, the reason for the appointment, and the doctors diagnosis is recorded. Depending on the diagnosis, the doctor may prescribe any number of medicines to cure the pet. Parents are charged for each appointment and must pay additionally for medicines.

During your interviews, the following attributes were also identified as being necessary for the system:

• Number of pets owned by each parent
• Price of each specific medicine prescribed
• Total charge for the appointment
• Quantity of each specific medicine prescribed
• Prescription price
• Medication list price
• Medicine name
• Total cash receipt amount
• Appointment date
• Cash receipt amount applied to a specific appointment
• Appointment length

Can you please draw an REA diagram which contains all of this information
