design a conceptual data model using ER/EER diagramming from the natural language description.

Part 2) You are asked to design a conceptual data model using ER /EER diagramming for the business functions of a group of dental offices from the natural language description given below. Be sure to consider the cardinality of, and participation in, each relationship. Also, be sure to identify all key attributes. Document any assumptions you make due to the imprecise nature of the problem specification. "Each office employs one or more dentists, hygienists, and receptionists each of whom have an employee number. Patients are free to use any dental office but, naturally, must make appointments in advance. A record of all such appointments is kept which specifies the patient's name, the date and time of the appointment and a list of services performed. Adult patients have a SIN (Social Insurance Number) but their children typically do not. Each office provides specific services (e.g. cleaning, filling, X-rays, extraction, etc.) to the patients and bills them accordingly. Performing certain services consumes supplies (e.g. floss, amalgam, X-ray film, etc.). Such supplies are purchased from a variety of suppliers each of whom is identifiable by a unique supplier code. The current amount of each type of supply available is tracked so that when supplies run low, a new order may be placed with the appropriate supplier. Patients are allowed to run accounts but interest is charged on unpaid balances after 30 days. Certain patients (and their family members) may be covered by dental plans that pay for all or a part of specific services they require. The dentists maintain a list of the providers of these plans so that they may bill them for reimbursement. For taxation purposes, it is necessary to track the yearly expenses incurred by each patient at each office as well as the amount paid under any insurance plans. For serious cases, the dentists also maintain a list of specialists in various areas to whom they may refer patients. The referral process is done first by telephone and then formally via regular post."
