Question

In the patient_disease table, which column is used to match with the disease_id column in the disease table?

1) patient_id
2) disease_name
3) disease_id
4) patient_name

Answer 1

The column used to match with the disease_id column in the disease table is the disease_id column in the patient_disease table, establishing a foreign key relationship.

Step-by-step explanation:

In database management, a foreign key is used to establish a link between the data in two tables. When referencing the patient_disease and disease tables, the column that matches the disease_id in the disease table would typically be the disease_id column in the patient_disease table.

Hence, the correct answer to the question would be option 3) disease_id. It is the unique identifier that would be used to connect patient records with their respective diseases, ensuring that the data is consistent between the two tables.

In the patient_disease table, the column that is typically used to match with the disease_id column in the disease table is:

patient_id

The patient_id column in the patient_disease table is likely used to establish a relationship with the disease_id column in the disease table. This establishes a connection between patients and the diseases they may have, allowing for the retrieval of information related to a specific patient's diseases.
