Help with Creating an ERD and Logical Data Model for a Medical Management Application

A social security organization wishes to develop an application to manage patients, their attending a generalist, and specialist doctors. A person is either a beneficiary or a doctor; a doctor can also be ill and be a beneficiary. A doctor is either a general practitioner or a specialist, with a general practitioner not being able to be a specialist and vice versa. A patient may or may not choose their attending generalist. A patient consults a general practitioner on a given date. During consultations, the general practitioner may or may not prescribe one or more consultations with a specialist. This application can be used by the social security organization to register a beneficiary, assign an attending physician to a beneficiary, record medical forms, and process reimbursements. All reimbursements follow a process and are 100% and 80% for general practitioners and specialists, respectively; these reimbursements can be made by transfer or in cash at the patient's convenience. Additionally, any doctor can, through the application, record a medical form, prescribe medications, and schedule a consultation with a specialist. 1-From your data dictionary come out with a corresponding MCD and MLD
