The relation shown in Figure 15.11 lists members of staff (staffName) working in a given ward (wardName) and patients (patientName) allocated to a given ward. There is no relationship between members of staff and patients in each ward. In this example assume that staff name (staffName) uniquely identifies each member of staff and that the patient name (patientName) uniquely identifies each patient.
(a) Describe why the relation shown in Figure 15.11 is in BCNF and not in 4NF.
(b) The relation shown in Figure 15.11 is susceptible to update anomalies. Provide
examples of insertion, deletion, and update anomalies.
(c) Describe and illustrate the process of normalizing the relation shown in Figure 15.11 to 4NF.
