Question:
Draw the ERD with cardinalities and keys based on the following description. A truck is identified by its Rolling Stock Number, and a driver is identified by an Employee ID. A truck does not have to have a driver and may have many drivers. A driver must have at least one truck and may have many. For this many-to-many relationship, an associative entity is needed. Design and add this third entity into your final ERD and assign a composite key as the identifier ?
