1. Consider the relation PatientOf and the functional dependencies below. Describe, with examples, how redundancy, update, and delete anomalies can arise. PatientOf (patient_no, name, address, doctor_no, since) patient_no → name, address patient_no, doctor_no → since 2. Consider a relation with attributes R(A, B, C, D, E) that satisfies the following functional dependencies: AB → D AC → E BC → D D → A E → B Find all the keys that contain the attribute A.
