#1. Entity Relationship Diagram #2. a. & b. One Room can be designated only one Room Type‚ whilst a particular Room Type can be assigned to several rooms (i.e. there may be many rooms that have double beds). Therefore‚ Room has a one-to-one relationship with RoomType and RoomType has a one-to-many relationship with Room. From the table‚ it can be seen that a particular room can only be designated as belonging to one type / category‚ thus confirming that Room RoomType has
