    Question - super keys

    Hello there.

    super keys are defined as combinations of attributes that can be uniquely used to identify a database record. Also, candidate keys are a subset of super keys, also called minimal super keys

    my question is: can foreign keys of a table used in creating a super key?

    Thanks in advance
