Assume we have a denormalized table R(mid, mname, eid, ename, age). Note that we renamed "name" attributes here to disambiguate. "mname" refers to the manager name and "ename" refers to the employee name. (a) List all of the (non-trivial) functional dependencies for the denormalized table R that are implied by the ER diagram. (4 points) (b) List all of the candidate keys for R. (2 point)
