Question
In Approach #2, which constraint (check Excel-10B and Excel-10C) would you use, and on which column(s), to ensure that a designer can only mentor at most one other designer? Explain. (up to 4 lines) Approach #2 will lead to some cells in column Designer MentorID and MentorWorkload having "null" values. Will this happen at all in Approach # 1? Explain. (up to 4 lines) In Approach #1, what is the problem of using only one column MentorID as the Primary Key (as opposed to using both MenteeID and MentorID)? Explain. (up to 4 lines)
