Hi.  I feel confused about the number among the relations when I making the ER model. 

For example, there are several employees working in the department. Dose this mean that there are 0 or many employees working in the department or mean that there is 1 or many employees working in the department?

Thank you.

Beat regards,

Hi Yaxin,

Where is the example from?
I personally think it is there are 0 or many employees.

Cheers,
Yu

Hi Yu,

Thank you for your answer.  There is no example. I just make an example by myself. Thanks a lot.

Best regards,
