ERD Design help meeded
- by Mobi
Hello guyz,
I am new to ERD and stuff.Earlier i was drawing an erd that issued me some problems.
the name of two entities in focus is "Bus" and "Passenger".What shall be the relationship between them. I think it should be many to many since one passenger can travel in many buses and a bus can give ride to many passengers.But one of my friend insisted that its a one-to-many relationship(A bus can have many passengers but a passenger can travel in only one bus).Plz let me know what's right.
Also , whats the relationship between a class,students.
Any help is appreciated.
