Entity relationship diagram (ERD) based on the Crow’s Foot or UML model:
A strong entity relationship exists between DOCTOR and PATIENT when a doctor can only exist in relation to one or more patients, and a patient can only exist in relation to one doctor. This means that the existence of a doctor is dependent on the existence of one or more patients, and the existence of a patient is dependent on the existence of one doctor.
In an Entity Relationship Diagram (ERD), a strong relationship between DOCTOR and PATIENT can be represented by a line connecting the two entities, with a crow’s foot symbol at the patient end of the line to indicate a one-to-many relationship (1:M).
strong entity relationship between DOCTOR and PATIENT in an ERD using Crow’s Foot notation:
PATIENT_IDPATIENT_CONTACTPATIENT_LNAMEDOC_FNAMEPKPATIENTPATIENT_FNAMEDOCTORDOC_NAMEDOC_CONTACTDOC_IDPK
The above diagram indicates that a doctor (represented by the DOCTOR entity) has a strong relationship with one or more patients (represented by the PATIENT entity), and a patient can only be associated with one doctor.
