I have this two diagrams and I need to answer the following question: Describe how the design class diagram will meet the needs of the dental clinic? Could anyone help?

This is the Dental CLinic information: The receptionists of the dental clinic are responsible for entering information about patients, including head of household information, insurance information, and number of office visits. The dental clinic business manager also maintains patient information, as well as dental staff information. The business manager responsibilities include printing invoices and sending them to the heads of households on a monthly basis, printing insurance invoices on a weekly basis, entering payment information, and compiling reports of overdue invoices. Dental staff are responsible for recording dental procedures per patient, and for running reports about dental procedures performed in a week or a month.
