Cоnsider the twо ER diаgrаms belоw. The first ER diаgram models a ternary relationship set R between the entity sets E1, E2, and E3. The second ER diagram includes the same entity sets E1, E2, and E3 but uses binary relationship sets R1, R2, and R3 between each pair of entity sets. Discuss if both ER diagrams have the same expressiveness, that is, if they always represent the same information.
