The answer is generalization.

Explanation:

In Database Studies, generalization is an approach in which two or more entities of lower-level amalgamate to create a higher-level entity, only if they have one or more attributes in common.

In this case, Student is a lower-level entity (along with Faculty, Staff, etc.) and Person is the higher-level entity, which is formed by the combination of Student and any (or every) of the other low-level entities.
