5. Conceptual Data Modeling Create a data model (ERD) based on the following business rules. You must - Identify all of the main entities. - Identify PK and FK - Identify all of the relations and connectivity. - Identify the type of participation optionality, existence dependency and relationship strength in all the relationships. - Resolve the many to many relationships using the associative entities. You must use Lucid chart to draw the ERD (and then copy and paste your complete diagram). 3-2 Physicians who work at a medical center see many patients. The center keeps each physician's personal information including id number, title, first name, and last name. The center also keeps each patient's id and her first and last name. Each patient may be seen by more than one physician, although on different appointments. During an appointment with a physician, which occurs on a particular date and time, a patient may be diagnosed with one or more illnesses associated with the degree of each illness. An illness has its unique medical name and common name that can be diagnosed in different appointments for different patients. Hint: - You may need 4 entities in your diagram: PHYSICIAN, APPOINTMENT, PATIENT, DIAGNOSIS, ILLNESS PHYSICIAN: PATIENT =M:N Use APPOINTMENT as an associative entity - APPOINTMENT: ILLNESS = M:N Use DIAGNOSIS as an associative entity
