Consider an Intercity Buses Travel Company. The company needs to manage the buses, the drivers, the departure and destination cities and their scheduling. The same day, a bus cannot travel to more than different destination. A driver may be assigned several buses. The same day a driver cannot drive more than different buses. Several buses can travel from the same city to the same destination the same day. Draw an entity-relationship diagram suitable for representing this information, in particular the connections between the main entities, their type of relationships and their related attributes
