ERD2 Thishis is ERD for project

4cd2 commented 4 years ago

I suggest you to pay more attention to "bus route". A route usually has stations or stops. What kind of relationship would that be? Can a route have multiple stations/stops and can a station/stop be part of multiple routes?

Also you do not have to save the ticket price. From the requirements you can see that it needs to be calculated. Please review that aspect.

ERD3 New ERD

Lizzy-Pan commented 4 years ago

The new one is much better than the old one. It's clearer.

I suggest that we create another table for all stations, as Jons mentioned, one route could have several stations.
