    Hi  giovannafnr88 ,

     

    For the criteria you provided,the relationship between Course to Tutor can be one to one or many to one.

    As the relationship between tutor and course is fixed as : one to one.

    So from Course to Tutor,the Tutor side should be one,but the Course side is not determined.

    All depends on the data structure.

     

    Best Regards,
    Kelly
