Give an example of a supertype/ subtype relationship by describing your example (not taken from a book but rather something you can think of in your business). Writing the business rule(s). And drawing the corresponding EERD. Please, each entity type (super and sub types) should contain one or more attributes on top of the identifier.

NB: make sure you take into account the following concepts: attribute inheritance, partial or total specialization, disjoint or overlap rules, and subtype discriminator
