So if I have this table: staffNo dentistName patientNo patientName appointment_date appointment_time surgery_no S1011 Tony Smith P100 Gillian White 12-Aug-03 10:00 S10 S1011 Tony Smith P105 Jill Bell 13-Aug-03 12:00 S15 S1024 Helen Pearson P108 Ian MacKay 12-Sep-03 10:00 S10 S1024 Helen Pearson P108 Ian MacKay 14-Sep-03 10:00 S10 S1032 Robin Plevin P105 Jill Bell 14-Oct-03 16:30 S15 S1032 Robin Plevin P110 John Walker 15-Oct-03 18:00 S13 Here the non-trivial functional relations include at least the following: staffNo --> dentistName patientNo -->patientName partientNo, appointment_date, appointment_time --> surgery_no Do you believe there are other functional dependencies? If so, what are they? If not, why not? Do you believe it would help to create additional attributes during normalization? If so, what are they? If not, justify why it's not needed.How do I draw this out?
